i feel you... ill never buy a motor like that again. im assembling my newest motor. forged internals, etc. only machining done by a shop. cant wait till this summer to get the new built motor in. ill have to settle with a stock motor till then.

so let me get this right. a stuck valve could be the cause for the excessive burning oil ive been experiencing? before i throw a new head on, i want to be sure that it will help.

Well, a valve stem seal could be the cause. A stuck valve could be the cause for zero compression.

Excessive oil on the valve (Stem seal) could be the reason for the valve to get stuck, if the oil is coking on the valve seat or face.

so this should greatly reduce the amount of oil consumption that ive been experiencing. since i have a new turbo, my old turbo was ruled out. and this stuck valve is currently the prime suspect. i guess ill see
thanks for all your help

my oil cosumption wne WAY down after I rebuilt the head and had new valvestem seals installed.

On quite a few of them the seal had completely desintegrated, and the head was stuffed with carbon from the burning oil...

i hope this is the case with me.... ive been through two heads before i got the latest motor. and after i got the motor, i still burnt oil............. never as bad as now though. for now, im just borrowing a buddy of mines head (thanks iceberg). but my june, ill have my new motor built.

The one that's one right now is what I'd say Ian's talking about, but if I were you, I'd go ahead and check the one that you're getting ready to put on, just to be safe ;).

ok thanks. i plan on using the head that im taking off for the new motor if its in good condition. i know its not a great idea to put the newer head on the motor without machining it, but if its in decent condition, what kind of problems could i expect?

Starscream: hahaha.... i know its a possibility and there are no guarantees. but i just need this to hold up for a little while. i dont want to spend a bunch of money to get this rebuild if im just going to have to do it in a few months on the new motor. are you saying i shouldnt even bother putting this head on temporarily?
IJ: any local machine shop could perform the hardness test? the head im gonna put on on thrusday is from a buddy of mine so im not spending money on it.

i completely agree with you. but im not trying to spend too much money on a temporary fix. i guess im going in circles here. i know what should be done, but i just want to get by for now.
thanks for the advice
