Help! (IMG:style_emoticons/default/headbang.gif)

This is pissing me off. Just for the record I did nothing to this motor (some one else did)inside the case. That said I have a 74 2.0 T-IV on an engine stand. I am just about ready to do the tin when I think lets double check the timing and get the distributor on. I start to turn the motor and find TDC for #1 then adjust the valves, then rotate the crank 180 deg. and Holly Crap there is like a 1/8th of an inch play in the intake rocker!! Piston is at or near the bottom. Does this mean what I think it means (cam is not in there right)? Some body, please tell me the obvious thing that I am over looking or doing wrong!

Thanks

We are confusing him....

the engines motion is clockwise. Thats why I stated that in my first post, so you would not get confused.

The engine fires 1432, clockwise......

basically when cyl#1 is a TDC, number 3 is at overlap and vice versa. valves cannot be adjusted at overlap.

OK I went out and spun it again looking at #3

Still facing the fan and turning it CW the Intake valve is remains open as the piston comes up (on any cylender). Surely this would push all the gas/air back out the intake manafold.

I have not worked on air cooled motors before what am I missing? Other than the hair that I am pulling out.

Grrrrrrrrr (IMG:style_emoticons/default/headbang.gif)

If that happens turning it CW and all the pushrods are seated correctly- The cam timing is off for sure! are you sure thats the intake valve? They are most inboard on both heads.

sounds like I might ned to ring you up before you tear into it.

Sorry guys, I was called away form the computer.

Yes I have checked repeatedly to be sure it is the intake.

I will tear down the motor tomorrow. What is the overall stand on the head gasket rings?
Lap the cylinders or use the rings. I have the rings in right now, but they are crushed I guess. I called Otto’s to see about ordering some and Steve said not to use them. The concept of no head gasket is very foreign to me, but what ever you all say, will be done.

Jake or anybody feel free to call PM or email. PM or email for # that way I will be sure to sit by the right phone.

Thanks again for all the help,

-Pete

SO?!?! The 914 Soap Opera. Don't keep us in suspense. This is better'n T.V.

Did Pete call Jake? Did Jake diagnose the issue? Will Pete's car run soon?

Stay tuned for another thrilling episode of "As the TypeIV crank Turns".


P.S. - Beats working in this miserable pit.

I have been away for a while, sorry it has taken me so long to post. I am at a dinner party on a friends computer (cable modem is very cool).

I did speak to Jake and he was very helpful. I did not get to work on the motor today, but I should get to it tomorrow.

I will take it apart bit by bit and photo as I go, as soon as I have it figured out for sure I will post.

I hope to have it back together by Sunday night.
What are peoples thoughts on lapping cylinders vs. cylinder head gaskets.

I have to go I will check back later tonight.
