Another Q45 saved!!!!!!!!

[elwesso]

As we speak, Jesda is getting his guides redone, FINALLY!!!!!!

Sorry I couldnt resist, his Q is just so golden © I had to post something...

[Jesda]

Booyeah, Internet access! Scott's getting it done right now. Its gorgeous out here in Iowa.

Wes, that pic is huge for the rest of us who are resolution-impaired; you can remove it as this one will suffice!



Chain guides, oil chain, ac pulley and belt, and I'll be good to go tonight. Im surrounded by acres of land and buffalo. What a nice relief from St Louis traffic.

After my drive, I'm still perplexed as to why every small farm town has a chinese restaurant.

Photos to come!

-Jesda

[elwesso]

Let us know where he in regards to the job. Where is he right now??

[maxnix]

Iowa, I think.

[911/Q45]

Every small town has an oriental restaurant because from 1945 to 1990 every other GI brought home an oriental wife and a taste for the food.

[Jesda]

Let us know where he in regards to the job. Where is he right now??

Front cover off... the guide was split into a couple large pieces, found one tiny piece of plastic. I assume the rest of the bits are in the oil pan. The chain was eating into the oil pump. But all is well now. Need to have the oil pan cleaned out soon.

Photos coming tonight.

Would now be a good time to say I told you so?

j/k

I'm so happy to hear that Scott is doing this for you.

[elwesso]

Hopefully everything worked out good!!!

Finally!!!!!

Got the chain guides done. All went pretty smoothly. The driver side chains were wanting to spin clockwise so it was kinda a pain to hold down really hard on the zip tie/lower chain to keep the top chain slack enough to put the tensioning guide in. I skinned up my thumb a bit but that's to be expected on any project like this. I didn't remove the water pump to save from having to put in lots of coolant we didn't have. Jesda left at 8:30pm or so after letting the silicone set up a couple hours and we let it idle and warm up for a bit to check for leaks. He has his cell phone and so far hasn't called up. I did hear a very light "snap" noise when removing one of the guides, from the guide slipping from the edge of the chain. It did have me nervous though for a bit although I had zip ties on and saw no real way it could have slipped. I also got slightly paranoid when I gave it a test start for 1.5 seconds and it rattled a bit but idled smooth. I'm sure the hyd adjusters just needed to pump up... but mine didn't rattle at all when I replaced its guides. Jesda's car and mine are same color, except his windows are tinted, different wheels, and mine's active susp. Hmmm, he should be home in the next 2 hours.

[elwesso]

Glad it got done good.....

Scott, he mentioned that some of the guides broke... How were they in comparison to your guides, and could you tell how much life they had left in them. From what it sounds like, they were on borrowed time..... What did you find, please elaborate more on the condition on the guides and the engine itself......

All in all, im glad it got done, and cant wait to see the patient in full recovery next week!!!

[ScottJackson]

the one guide was in pieces and the other was cracked in one spot 3/4 of the way thru. The chain had wore into the oil pump and took half a head off a bolt holding the pump in the motor. It was all ok though as it hadn't worn into any moving parts or empty spaces. The chain was very loose with over 1" of slack play in it. I truly believe his motor was living on borrowed time. And that in itself made me feel a bit more at ease if something went wrong, because if I hadn't made an attempt at it then it would have been a gonner soon anyway. After putting in the new guides but before the front cover, I turned the motor over twice and checked over the links on the broken side and they were good. It's too bad I don't have a shop with a lift so I coulda dropped the pan... but I did find probably over half of the broken guide in 3 or 4 pieces other than the two tabs still attached to the bolts that hold the guide. Jesda got some pretty good pics during the project and they will surely be posted soon. These Qs surely do deserved to be saved from the chain guide disaster.

What kind of silicone did you use? I wish I didn't have to wait 24 hours every time I use RTV.

The snap was probably a cam snapping against the chain...one of the springs was putting a moment on the cam, and it gave all of a sudden. Nothing to worry about as long as the chain didn't jump. Sounds like it's running just fine. Seems very few cars have a broken guide on the passenger side. Good job!

And the guide pieces in the sump....just evaporated??__________________Brian1995 Q45 & Q45t & 2000 Q45

Well, I must say I actually had a good time. My fascination with the elusive chain guides was finally satiated, met some really cool people, and I ate some -damn- good buffalo.

So here's a photo essay.Half of it is relevant and half is just me sharing a road trip:

Macon MO. With signs for Marietta and Macon I thought I made a wrong turn and ended up in Georgia. I went to a Casey's gas station, which topped out at 89 octane. I went in and asked the lady, "Do you have 91 octane?"'You mean the gas?'[brief pause] "Umm... yeah? [pause, stare] Where can I find that?"'I dont know.'No biggie. I was getting surprisingly good mileage this time around at 18mpg (was getting 13mpg during my drive to Lexington).

Yay.

Scott's other Q.

Fish.

[Jesda]

Preliminary look. On the right behind the chains is a broken guide. Up front is the oil pump chain, which is rather loose.

You can see the broken plastic guide on the right.

Close up of the broken guide.

Guide piece.

Passenger side, still in tact but cracking in the middle.

Another guide piece.

Same guide piece, flipped.

Oil pump chain removed, timing chain guide zip tied on the left. Notice the slack in the chain. At any point the chain could have jumped. Also observe on the right where the chain ate into the oil pump and a bolt.

Close up of zip ties used to keep the chain from moving.

Passenger side guide, -seems- in tact but is cracking in the middle and feels brittle. I could not break it by hand, but a light impact with any object would have shattered it. Dated Piece is dated June 91.

Same guide.

New guide installed, passenger side.

[Jesda]

New guides! Backed by metal.



Oil pump chain reinstalled, new guides, no longer all that slack.

More new guides.

Videos (Nothing relevant, so dont bother if youre on a modem):

Wanted to show WOT... bad lighting and cops everywhere so I backed off.

Intending to take some stills, took a video by mistake. What would Simon Cowell say?

[DAEDALUS]

Good to see Jesda. Now get some sleep!

[Jesda]

So in all, everything is GREAT. No leaks, drives perfectly. I recommend Scott's services to anyone!

And southern Iowa is surprisingly beautiful at this time of year.

[elwesso]

You need to rename the video files without spaces..

glad to see it got done...... GOLDEN

[elwesso]

Scott, what kind of HU do you have in this car.....?

[ScottJackson]

the pieces of old chain guide that weren't found were probably disolved by the oil and then sucked thru the PCV system and left out the exhaust.:pface really though, I don't have a lift and Jesda will get his pan dropped and cleaned out soon as a seperate job, maybe when Wes is doing the steering rack bushings and such. The head unit is a Clarion ADX5655Z tape and CD double DIN. I have Cadence UltraDrive 6X9s in back and have JBL GTO 5.25" components coming soon for the front. I also have a clarion 6 disc changer but need to get the CeNet cable to hook it up and then I'll remove the factory Sony 10 disc and sell it. I don't like the display of the Clarion, way too disco but it's what I had sitting in my room and figured I might-as-well use it. I'm thinking of using paint to paint the plastic of the display where the little frequency band lights bounce up and down all the time, just to kill off a little disco even if it looks tacky with paint on it. I'll probably switch to a Blaupunkt HU sometime.

I really don't post here much but I am a freind of jesda's and I am the one that helped jesda find his 92 when he first bought it a year and a half ago. I remember when we first found out about the chain guides and how jesda felt like he was sitting on a time bomb.

He and i have discussed at length about the chain guides and when and how he was going to get them done.

I'm just so happy that he got them done and what great pics. I never really noticed how much of an incredibable difference there is between the all plastic guides and the metal backed ones.

Good job, Jesda and excellent work, Scott. I'm impressed that it only took you around 5 hours or so. From what I have heard, guides usually take much longer to do.

And whats the deal with that comment, brian, about the guide peices being in the sump. Geez. They know about that of course. Jesda got the most important part done, now he can worry about that later, at least the chains won't slip and grenade the motor.

All in all, great work. I was sitting on pins and needles waiting for this job to be completed and jesda to arrive home with no scarey stories about somethign else going wrong. (i felt a tiny bit responsable for him having to worry about this chain guide issue since i was the one who found him his 92 q45 way back in the beginning).

Well, if you read enough of the prevoius posts about the chain guide problem, you will discover that missing pieces can be decimated sufficiently to clog the oil pump intake screen or even to be ingested into the oil pump, degrading its capacity and thus jeopardizing the whole (just repaired) engine. That is why the oil pump is always scrutinized for excessive wear. Oil pump chains are often replaced because of chain guide debris lodging between them and the sprockets or front of the block. There is a whole thread on how a failed guide piece caused a oil pump mounting bolt to back out.

Scott did a great job, but it is impossible to safely lift the engine (while supporting the transmission) without a lift and the other tools in a professional shop in order to remove the oil pan. As Q45tech says, one must account for all the pieces of the failed guides.

Everytime I see a G50 on the road, I am struck by what a classic car design it is. Often times, I even have to remember I am driving one. I want them all to stay on the road as long as possible.

Now that Jesda has conquered his fear of chain guide replacement, we as G50 owners must help him overcome his fear of failed chain guide parts retrieval. __________________Brian1995 Q45 & Q45t & 2000 Q45

The major battle has been fought, but the war is not yet over!!!!!

(the war is never over)

[Q45tech]

5 hours is a good time. T3 can't do it that fast but then we spend time cleaning the inside cover and removing oil pump and looking inside.

Didn't see any comments about changing both chain tensioners-you did change them I hope?

[Jesda]

Yep. Everything on Joe's parts list (minus new timing chain, which I did not order) was installed.

[ScottJackson]

or so you think it was all installed.... JUST KIDDING! Yeah, he saw the new parts as they went in. I didn't clean out the front cover, just cleaned off the edge where it meets the oil pan and around the front seal to keep it clean for putting in the new seal. Also cleaned up the edge where the silicone seals up and the two inside holes seal against the block. It took 5 and a half hours. As for the what type silicone farther up this thread, I just used the nissan gasket maker. I know it's supposed to set longer but I put it on in a quite thin bead to help it cure as soon as possible and to keep it from squeezing into the crankcase and become a potential oil pickup blocker. What I do is after it's been set for 2 hours I start it up and make sure it went right. Let it warm up a little and then let it sit a few more hours. Since it doesn't really have any pressure against it, assuming the surfaces were cleaned of oil, it should be just fine to drive until it finishes curing. Granted, I would prefer to wait 24 hours to run it and I definately would if it were going to be seeing any pressure, but for this it seems fine.

[Mr1der]

OMG I demand more pics of that Stang!

you got some neat cars Mista Jackson, I am for real!

so are the metal backed guides a near permanent fix on this problem?

and that looks almost like a DIY job coming from a TN idiot like myself, how hard is it?

[Q45tech]

Now that members have more places to get the job done, besides the dealers.........fewer and fewer excuses.
