Well I have a fully built and bored out GSR motor... pretty sure the head gasket is blown.. would those compression numbers be conducive of a blown HG.... any suggestions thanks... i lose alot of coolant without it leaking and burn alot of oil.

It could be evidence of a blown headgasket but the numbers are still too close to make an educated decision. At this point the only way to really tell is to pull the head and check.d

 

the #s all seem pretty close... i wonder

 

I used a cometic head gasket when the motor was put together.. .think i will swap it out with a stock honda gasket.. unless there are better suggestions... it also has a block guard on it

 

How thick of a Cometic gasket did you use, and looking at your numbers I'm assuming you're running all motor. Consider the Spoon headgasket.

 

i dont remember the thickness... yes its an all motor setup... it was a triple layer gasket...
I noticed boring it out to a 2.0 definatly gave it some more torque..

 

But is the Cometic gasket thicker than stock, thinner, or stock thickness.

 

believe it was thicker

 

not trying to say you do not know what your doing. But did you get the car to normal oper temp? Sometimes people forget

As a general rule of thumb, thicker headgaskets tend to have more problems than thinner ones.

 

Before we did the compression test you mean?
i dont believe it was at the complete normal temperature... that could change things.???
I am not pretend to know everything because there are a lot of things i dont know... so any info is appreciated

 

compression test should be run right after the car is shutoff after it was totally warmed up, with all plugs out and WOT. gl

 

Those numbers look normal to me.

 

I think I will retest them tomorrow morning once i take it to the shop... Think i am replaced the HG anyway.. i burn way to much oil and lose too much coolant.. plus its leaking out of 3 cam seals, vtec sylonoid (sp?), and was leaking out the bottom of the distributor...

Those numbers don't look very bad at all. Of course I just pulled my brothers head for similar numbers and the gasket was just barely blown. He had overheating issue though. How do the spark plugs look?

 

But the biggest issue here is that he's loosing coolant and burning oil. I believe it's worth pulling the head just to make sure.

 

You really need to get a leakdown test done to fing out what your problem is.

Are you burning off the coolant or is it just mixing with the oil? It sounds like you have some major problems. Burning oil and losing coolant combined is not a good thing.

Check to see if the coolant is contaminated with oil and the same thing with the oil - check to see if it has coolant in it.

 

The 2 spark plugs on the ends 1 and 4 the prongs were white... and yes I am having an Overheating problem too.. Rather Badly... radiator replacement and thermostat change didnt cure it...
might do a leakdown test tomorrow

 

yea things dont sound too promising,but good luck.

 

could it be worse then just a blown head gasket?

 

Worse case scenario, it could be a cracked sleeve... but I doubt that. Pull the head and have a lookie, replace the head gasket if all looks well, and keep your fingers crossed.

 

thanks, new sleeves went into it 5k miles ago i did a complete motor build.. dont think i skipped anything.. just no hondata yet

 

Maybe your torque wrench is off. Thus the head bolts were too loose?

Now that you say it is overheating I would definetly pull the head.

Worst case scenario is that the block or the head are cracked.

 

the cometic all-motor hg is thinner than 82mm, the boost/nitrous hg is thicker than 82mm. i had the same problem in my 94' b18c1 before it went...check the gaskets in the sparkplug tubes and some of your vac lines to see if there clogged.
