Trouble with my motor head gasket?
I am posting this in the FI sectiion because I am wondering head gaskest people are running on head and cam stock bottum end cars running about 8 psi.
but let me explain my problem.
Ever since I put my car together this year, new heads and the procharger my car has been smoking(white). I keep fowling plugs 2 and 8. cound that the problem was I was getting oil in these cylinders. I thought it was cause my rockers bolts might not have been sealed well. so I resealed the rockers and they still fowl. I am thinking maybe valve seals.
I got my car tuned last friday the 13th. And while I was on the dyno at high rpms I kepts pushing the oil dipstick out of the tube. I thought I just needed to open up the pcv system. so I brought it home and put some breathers on it. Now at idle it smokes like crazy out of the breathers. I preformed a leak down test and found that 6 of the 8 cylinders were losing about 80% of the air I was putting in them. so fearing I hurt the motor I pulled the heads back off the car. all of the pistons are ok none are damaged. but I also notice that the when I pulled the radiator cap there was preasure in the system and it was low on fluid(had been sititng for 3 days) so I am thinking maybe I blew a head gasket or have a warped head or something. Not sure looking for ideas
BTW I was running a MLS gasket. Should I change gaskets and put it back together and hope for the best. I will check the heads with a straight edge.
Or should I bite the bullet and forge the bottum end of the motor
Also the motor only have 54k on the short block
Thanks

I'm thinking that if after 3 days of sitting you still had pressure in your cooling system then your head gaskets must seal pretty ******* good.
When the plugs foul, are they oil fouled? Post a pic of a plug, that will tell us.
Make sure you didn't damage a piston and/or ring.

I will get some picture of the plugs later I know they are oil fowled because both of those intake valves had oil laying on top of them. These 2 cylinders the 2 that I had a good cylinder leak down test on like 30% the other 6 I had 80% leak down on. But the car did smoke white I had lost some coolant. The tops of the pistons look fine nothing appears to be damaged I can't really tell about the rings. I Am not sure what to do know
