Hold on emarknot-

You cannot just turn the cam or cranks if the belt is not on. Your wording is going to mislead him.

Dashan - can you put the crank pulley back on the key, and take some pics so we can see what's going on? Get all the timing marks in view.

dashan

How to set 3 marks? A small write up would be very helpful.
I am confused whether in which direction (clockwise or counter clockwise) I should turn the pulley.

deanbrown

Here is a pic of my L cam at 50 degrees past TDC: You can see a white dot on the engine aligned to the cam mark and belt mark. If your crank is at TDC+50, then you should be able to turn your cam back the way it came, to this position, but DEFINITELY NOT all the way round the other way!

emarknot

yes......you..........can !!!!!!!! without the crank pulley even on the car !!!!

to set the timing mark on the crank, without the crank pulley installed, you simply put the crank bolt in,tighten by hand, when it stops, use a ratchet or wrench to turn the crank.

same as the cams.

people way over complicate this entirely too much.

emarknot

3 timing marks....1 crank, and 2 cams.

deanbrown

But its an INTERFERENCE ENGINE! You will crunch the pistons into the valves!

dashan

crank at TDC+50 10 characters

dashan

L cam 10 characters

Here is a pic from my 96 LS400 service manual:

R cam 10 characters

emarknot

no....you wont...dont over think....dont over complicate




you guys are killing me!!!!!!!




im just going to stop posting all together. I do this stuff for a living



be thankfull.you dont have a true 4 cam engine. we have a master/slave ....or..... primary/secondary cam......depending on who you ask.

1 crank, 2 cams- a belt marked as such.

dont over think it, the belt is a 10 minute job.

all the labor is removing and installing everything before and after the fact

LOL you had too much beer tonight? Do you by any chance see the NOTICE - Do NOT turn the crankshaft pulley message, just above your last post? Do you think there is a reason for saying that?

Dashan, what the manual suggests is that you can turn the LCam a little to get the timing belt on, if the crank is at TDC+50 you have some play. You also have to take up the slack by turning it enough to tighten the belt on that side, to get the other side on the RCam. It has a pic showing this with the cam tool in one hand and the belt in the other.

emarknot

a 350 degree turn is not the same as 360.
360 is a damage point....that and beyond.

a 360 degree is damage on an interferance motor.
not 350.

you backyard guys pride so muxh on pride, but its sooooooo overcomplicted. 3 days for this-4 days for that. not following through a simple procedure.

im going to tell my boss tomarrow to fire me because the 7 years ive worked for him with a 4% comeback rate, im dumb and cant do anything right.
whoo hoo, guess im getting a 3 day weekend!!!!

the 89-97 are true "4 cam" engines, the cams are NOT paired. 98-00 have a gear pairing the cams on each bank for the VVTI sync.
