We aren't sure if it's rings or head gasket....all I know is I have next to no compression on #6, the #5 and #6 plugs are completely carbon'd up, and I'm dripping a small amount of (I think) coolant from towars the driver's side, but I can't tell from exactly where.
I'd much rather if it were just the head gaskets, since pulling the motor is such a bitch. Of course if we do pull the motor, then I can try to make that Teflon crank scraper work.
Can you elaborate on the oil-in-the-spark-plug-hole thing? I've never heard of that approach before.....

If you add oil to the cylinder before the compression test, if there is a ring problem, usually the oil will temporarily seal that up and your PSI will go up.

i am thinking about getting my heads milled but how much performance will i gain and do i need to change anything like different gaskets or smaller spark plugs

Milling is a waste of time unless you need to clean up the surface and make it flat again. Even .020" off won't make a big difference in compression (.1 at best).

Cliff is right, if you squirt some oil in there, it will seal the rings better. If compression doesn't go up, its not the rings.

my car temp goes up and down dose anyone know about that

WhiteV6 · 06-08-2009, 02:15 AM

its not performance related for one. Check your coolant level and for air in the system.

crackakam · 06-08-2009, 02:16 AM

coolint level is full how do you get the air out of the system

Well since were going off subject lol Can anyone tell me how much power my 3400 alero would need to outrun a 2006 Pontiac GXP thats bone stock and what i would have to do to it to gain that power?? Ive already got a tuned pcm from mpracing,obx headers,Ebay WAI, Running the AC DELCO Iridium plugs,No Catalytic Converter,Headers back 2 and 1/2" exhaust with a borla muffler.

Wow you actually got something out of mpracing? Id advise not going through him again.

WhiteV6 · 07-25-2013, 10:37 PM

mpracing couldn't tune a bicycle. Agreed, lucky to get a damn thing from them.

I don't know what a gxp runs.

Turbo...nitrous...something more than what you have , 06 gxps have broke 13s stock, most run low 14s

Milling is only going to really help you if you have major work done to the car, otherwise, it's not really money well spent. Now a 3 angle valve job, that's worth the $$$

I answered his question though

02AleroGLS · 07-26-2013, 11:46 PM

Yeah it took forever to get my pcm from him though,like over 3 weeks! I had to bug the hell out of him every other day when 2 weeks cause he was ignoring the hell out of me! I really thought i was screwed out of $150.00.. But. I finally got it.. My car is basically gutless from a stop untill i get to at least 4,000 rpm's then it pulls pretty good till around 6,000rpm's then when i shift into 3rd gear its basically balls slow again till around 100mph.
