so i'm off on timing or wat?

[silpena]

ok i've searched and searched but when i reinstalled my chain from the crank it was was perfect at tdc but after i cranked again it wouldn't line at tdc when i first started. Do i have to crank it over and over hella times to get it back where it was? also when i installed my cams they were set up just like in the jwt insructions i cranked the ending twice for one full cam rotation and the cam gear points are where they were but the color marks on the chain isn;t. Its allways different. Should i worry if it isnt there is a little slack but that becuase i no oil in the oil(removing oil pan to get washer out in oil pan :/) well yeah.. i figure its becuase the tensior is not full working so i guess that figures that but would that cuase my marks not to allign with the cams? I need to know cuz i'm gonna start this baby after 4 months of trying to put it back together. I'll try and get pics if i can a camra from someone to barrow. Also i have an idea wat if i set the cams correctly with the color marks right crank the engine then back to tdc then mark the cams with the chain to the idler sprocket at tdc and it all lines back when i crank the engine should i even care the color marks don't even line up? I think it wouldn't matter unless the marks should be there no matter wat.

man, my post is hard to follow guess i should have looked it over first...

wut in the hell.....From the beginning.Set up your timing marks to TDC. Crank and cams (dont know what engine you have, but I am confident that you do.)Install the chain (hopefully a new one), the side with the tensioner will be your slack side.Hopefully you used assembly lube when installing the cams, rotate the engine manually for a full 360* .Check your alignment marks. Dont worry about the colored links on the chain. (because of the slack side 99% of the time they will never match up.Assuming everything clocks out okay, spin the engine again 2-3 full revolutions to verify.If for some reason, the timing marks don't true up, reset the chain, and this time count links before and after rotating the engine. The FSM will give you # of links between certain points. Other than the wrong chain being used, the timing will always true up.

LOL, guy you're hilerious.

i did the same thing when i rebuilt my first KA. and NO, it will take several hundred if not a few thousand rotations to get the marks to reline up witht he marks on the chain. but lots of people wonder.

take a picture anyways, its easy to be off one tooth, an it never hurts to have another good TDC picture.

yeh i know it was confusing buti have a dohc. ok so i know to rotate it 360o degrees i do from tdc and it comes where it started i need to count the number of points on the chain its at. and yes i use asembly lube and all i need to do my timing again i just don't want to bend the vavles i'm not that rich so i need to do this right the first time. I'm gonna get a new chain from nissan i suspect it's slightl worn out and i'll get better results when setting the timing.I used the jwt site for it so it should be allright idk wat was up with the color marks on the chain. Also the first time i set the idler sproket wth the crank it matched up with marks on the chain then after rotating it it would i figured since it was a tdc i checked by setting the oil tube dip stick on the #1 piston till it was at the top i thought i could put in the cam all to jwt specs then rotate 2-3 times full 360 degrees and no matchie on color marks but cams seem to be where they started and cam lobes are facing away so this time i will make marks with paint and rotate it to see if they match or use the chain and count the marks between the cam key points. wooh hope this helps with my Q i know i'm hard at explaining things.

did you even read my post?

[gthammers]

Yeah DJ - I think he skipped your post,

I kinda freaked out like this guy when I did this the first time. Nothing was hitting internally so I kept cranking until it lined back up. I think something like 20 (maybe 40) complete engine cycles does it. By this time I was just curious!

Anyhow - once you turn the engine - forget about the chain marks.

#1 TDC and cam position like on Jim Wolf and life is good, or at least your valve timing is!

[silpena]

ok cool i'll just go with it and see wat happens. all and DJ i did read i just kinda get anxious and ask the same thing again in sorta different ways sry.

[DjPantsSpecR]

yep exactly, i know youre nervous, im not coming off as crass.

But you can start and run the car with the cams off (and the distributor as well) by a tooth, it wont be the end of any valves. 2 teeth will bend a valve, but not one.

so if youre still scared, doa compression test 120psi would indicate being off a tooth and 170s should be spot on.

and you can still take a picture, we will look.

but yeah the position of the cam lobes is identical to the JWT and the sticky. Now jsut make sure you know what TDC is on the crankshaft, second mark from the LEFT-most mark.

[silpena]

ok cool i'll try and barrow a camra from someone to double check it. Id didn't know about the compression testing that will help me out too. How would i do that. Just the same as any ol' compression testing? Do i crank the engine by hand? and read off the compression numbers then iff all good 170 then go ahead and start and if not then need to fix the timing.

[DjPantsSpecR]

yep regular comp test. but use the starter tocrank it. pull the injectors harnesses, spark plugs, and fuel pump fuse.

you're looking for 160-180psi

[silpena]

ok cool thaks man.
