Re: Fel-Pro or Mr Gasket one piece oil pan gasket?
I have had the earlier version of the felpro 1pc pan gasket on my 396/bbc since august 2001 and its been decent thus far .
It's had only a smideg of seepage on front t/cover corners to pan interface thats just enough to pick up some dirt & turn black over time which wipes off easily,but it never seems to leave drips of oil on the garage floor floor.
But i had the std type felpro 4 pc oil pan gasket on the motor from 1979-2001 and it was leaking a lot 22yrs later which was the reason i pulled the motor to fix it.
But since i did an econo rbld on the motor in 1979 for $600 (was only 23yr old kid at the time) i decied to go thorugh the motor again while it was out ,i spent approx $3,600-$3,800 on machine work & parts this time arround & i went through it completely.
But i have to admit the motor was still running fine propr to pulling it to fix leaking oil pan. It was not using much oil ,had 30lbs idle & 58-60lbs at cruise for hot oil pressure but i still didnt trust that if i only fixed the pan gasket that a bearing or head gasket etc wouldnt let loose a yr or 2 down the road having to pull it out again.
BTW,the early version of the felpro 1 pc pan gasket didnt come with any paperwork stating bolt torque and it wasnt on the box either. Back in 2001 when i installed the gasket i didnt have the intranet and tried tocontact felpro to ask what correct trq was for pan bolts but could no get a holdof them so i used stock gm oil pan bolt trq.
The stock trk really crushed/compressed the heackout of the gasket so i backe it off some to where it looked reasonable and went with it.
Then when i got intranet a few yrs later i contacted felpro and long story short found out the bolt torq for the felpro 1 pc pan gasket was approx 1/2 of what the std 4 pc pan gasket bolt trq was .
My early version of the 1 pc felpro gasket of 8 yrs ago didnt have trq limiter sleeves either so if someone was to have over torqued the earlier version 1pc gasket by 2x using stock gm pan bolt trq value thats why it could crumble/split because its been over torqued by 2x what it shold be.
