Found broken parts while resealing valve covers (was: Well that plain sucks)

[Chubs]

I decided to finally start fixing up the Q I bought. Pulled the plenum yesterday and today it was time to reseal the valve covers. Then I found this....

[elwesso]

holy crap..... a broken rocker arm(s)? Looks like on the intake cam on the #2 cylinder.... thats messed up.....

That motor is NASTY looking!!!

[CrimsonQ]

wow look at the oil change interval on that.......

so ya gonna part the rest?

[Jesda]

Holy ****

[Chubs]

Well I have been buying parts from Pop to get her back in good running order. So far I bought the followingInjectorsChain guidesO2 sensorsKnock sensorsZ32 brakesMurano wheelssome interior parts and a few other things.Not real sure what I am going to do with it now, might just stick a motor in in and call it done, or possibly a new head. Sad part is the car only has 95k on it, poor thing

[Fridge]

Wow to bad your in TN I have my old engine sitting here waiting to be hauled off.......

[ceningolmo]

Vulture...

Anyway... wow. Now I'm nervous about what I am going to find when I reseal valve covers on the green Q. Yikes.

what kind of shape/mileage is it in? If its in good enough shape i could probably come get it from you.

How much of a pain in the *** would it be to swap in a 96 motor in my 90 Q?

Major changes in 94. And 96 is OBD II. Wiring, electrical, etc.

You need to find a 90-93 motor and do the guides.

How much do the valve cover gaskets cost?

I think it will be the next thing for me to do on the Q.....

And I am wondering if they would arrive in decent shape if I have to get them from Joe! :hide

[ceningolmo]

9093 Didn't have gaskets for US models. They are sealed with RTV. I'm not sure if yours will have gaskets or not.

[Chubs]

Well I already have them so I guess that will be the way to go.

It is the engine that came with the car. It was already pulled when I bought it. If you want tomorrow I will check it out. I have the valve covers off and did not see any damage so it might have the parts you need. By the way I am close to Houston TX. It might be easier for me to pull the parts and ship them to you.

im sorry to say that ive done that, i blew out 3 roller rockers and 3 lifters, blew everything apart, they aint cheap either

[elwesso]

how do you blow out rocker arms like that?

If you would check that out I would appreciate it very much. Let me know and I will let you know which way I would like to go.

[TBrack]

Sweet, someone else from Knoxvegas! I think my valve cover gasket is about to go out too

[ScottJackson]

I'd just cover the valve cover hole with rtv and then put in a new rocker.

[Q45tech]

Ocassionally the early 90 engines did that on #2 intake, if oil wasn't changed at 90 day increments. Never seen it on 91 or later but the parts are identical?

From your pictures this is very evident all that varnish and wear.

Very interesting you've seen that before tech... Do you have any explination why other than OCI's (which is a valid reason)...

[Chubs]

The coloring on the pic is a bit off due to a bit of photoshopping, it is not nearly as copperish as the pic shows. I am guessing tha the no 2 rocker took out the other one.

[carfrk666]

i

well in my case it was quite difficult to do, first you start off by spending 3 grand on parts to rebuild the motor, then neglect the hydraulic lifters and bleed them down, and vwala, u start the engine and the cam comes around and smacks the rocker with the lifter not pumped up and it cocks the rocker sideways and does it again and boom, u have one hell of an expencive repair, its just that simple

I have a nice set of heads from a low mileage 1992 engine you could have for $200 shipped. They have no sludge or noticable wear.

[Q45tech]

Just clean the varnish and HLA and replace with new non worn followers.

The amber edge on the cam lobes tells the tale.

[Chubs]

Not to sound like a complete retard but what do you mean by HLA?In your opinion would I be better off just slapping a new head on there like what Q45 Denver has? Posibly even do both the heads/head gasktes and timing chain while im in there? Or replace the two rockers and one or two lifters?

[Q45tech]

Adding 15 hours to a 1 hour job plus the head costs is not something I would do.

Swapping heads requires retiming the engine [chains] new head gasket, etc. head bolts.........they are use once.

Not knowing the HLA term proves you haven't bothered to read page em38 of fsm

I have had no reason as of yet to read it cover to cover, just skim through it to see what I need at the time. SO you think that it would be easiest to drop in two new rollers and replace the lifter(HLA) on No. 4. weld up the valve cover and call it a day? The only issue I would have with this is the damage to the cam lobe on No.4 and the part of the rocker sitting in the oil passage below the No. 4 exhaust valve.

What is the mileage them and do they have their valve covers?
