blown headgasket?

blown headgasket? i took my head off and the three cylinders away from the the timming belt were all dirty full of carbon, and the one closest to the timming belt was clean, just wondering was there water getting in the cylinder ?

Why did you remove the head? Should have done a compression test first before you took it off. But a clean cylinder is usually because water is getting into it and steam cleaning it.

check your reservoir bottle if you havent emptied it. If its totally blown there should be oil in your coolant. Or it will be brown and milky. You really should have either done a compression test or a leakdown test to save yourself some time, and hassle by taking off the head if you didnt need to. But I guess now that you have it off...

whoops i did do a compression test , just forgot to put that up tthere, numbers 30-80-110-160, thats from left to right!, the head is in good shape no bent,cracked,broke vales, it might need to be mechined!

leakdown test? just put some coolant in the cylinders, rght?

NOOOOOO.

You add oil in the cylinder (like a tablespoon or so).

No coolant in cylinders.

Yikes!

Also check your oil, you should be able to tell if it is coolant and oil, or just oil by looking at it closely.

okay thank you! if it leaks bye blown rings right?

A compression test tells you which cylinders are not operating properly. Adding oil to the cylinder while doing a compression test tells you one of two things, either the compression number increase significantly, which means the rings are bad, or it doesn't change the compression, which means you have a bad headgasket, or valve seals (or bent valves).

A leak down test is different. this is when you add air pressure into the clinder (need a special sparkplug air nozzle adapter for this. You can listen for where the air is coming out and it will tell you what is bad, headgasket, exhaust valves, intake valves, or rings.

When I did a compression test on mine I got 90 across the board give or take a few psi. When I added oil not much changed and we just put on a new hg. When we did a leakdown test and applied 100psi not 1 bubble came out of the coolant. Your saying someone can still have a blown headgasket after that?
