Soooo

Car has been sitting for a while during a motor swap. I swapped in a 60K mile used motor i picked up. Put my cam and valvetrain in it and slapped it in. Flushed the motor out with about 5-6 quarts of oil and go it started. Let it run for a total of about 5-10 mins hunting down a vaccum leak/ idle problem. Got that straightened out and pulled a vlavecover to adjust the rockers and i found MILKSHAKE! s0o0 I pulll all the plugs out and all look about the same except for #6. Suspecting an obvious blown headgasket i ran a compression test on the cylender and 2 other random ones... The two randoms came in at 185 and 185. And the #6 registered at 195! and did not bleed down after 5-10 mins. So what do you guys think? I dont suspect any of the cylinders due to the fact none look "steam cleaned". Could the water have come from somewhere else?




Thanks in adavnce

 

You need to do a leakdown on all cylinders. No guesswork will remedy the situation. A leakdown will be the most accurate in telling you what is happening whether it be a blown head gasket or a cracked block/heads.

 

you may just have condensation under the valve cover, drain the oil and see then u would know for sure

 

try retorqe on headbolts

 

yes, could just have been a build up of condensation from sitting so long, change the oil and drive it then check again
