Rebuilt head, car not starting, help!

[nando]

you don't have to remove the cam gear, it will stay on without the key. in any case it's easy enough to check.

[hella 325]

hmm i thought the key and the cam geear went on with the same torx bolt.

[nando]

they are, but the cam gear fits over the cam with it's own key that will hold it in place.

[hella 325]

hmm interesting. do you have pics of them? You have me intruigued. But i have checked the rotor position and its on tehre right. Just curious how that happens. Always trying to learn things... :D

[DaN]

I always like to know how the compression is across the board.

[Good & Tight]

Are the valves adjusted ?

[hella 325]

valves are at .010 and compression is 151+-1 psi accross all 6

[hella 325]

bump its a timing issue, im pretty sure i know that much. If the marks line up. What could throw timing this far off?

[robmespeedy]

It sounds like a timing / firing order issue.

The firing order is 1 - 5 - 3 - 6 - 2 - 4

Also you could have the motor 180 degrees out; take out plug #1 and turn the motor until you feel the compression, make sure at this point that the rotor's pointing at the #1 cylinder.

Hey nick , im also having the exact problem and i do believe my motor is 180 degrees out . would this cause me to have low compression ? 60 psi across the board .

[hella 325]

its impossible to be 180 out... cant do it... unless u cram teh cam wheel or crank wheel on wrong... but there is a male peg on the back of both that goes into the cam or crank... if that is filed off i guess its possible, but unless the peg is gone... the wheel will be correct or tilted to one direction.

EDIT: that is if your marks are lined up... if the timing marks are 180 out its totally possible...

[bimmer8604]

are you using the bently manual? in the bently it says to line up a mark on the crank with a mark on the case, but in the bently its the WRONG mark. There is another mark on the crank that you are supposed to line up. one of the instructers at school was having similar issues. dbl check and make sure you have the correct timing mark lined up with the case.

haha really? whats the wrong one it has in it? and whats the "correct" one? just curious, i dont have an e30 or a manual with me... thanks.

[bimmer8604]

Not sure, i do know that there are two marks on the crank there, and its the other one that the bently says it is. my bently is down in the garage, and im too lazy/naked to go get it.

whoa... to much info.. haha, yea i know the 2 ur talking about, one is a molding lip thing, other is the accuall line.. i know what ur talking about now.

[Insanity]

You said you rebuilt the head? I'd be looking for problems in the head, then. Check your compression on all cylinders. Your cam timing could well be off, or there could be a valve problem.
