Im working on a couple MK IV Bowtie 10.2 engines, I ordered Felpro 1884R and the front and rear sealing area seems to be to thick, the pan rocks back and forth and the rails are about 1/4 inch from the block, are these the correct gaskets ?? they look to be stock mercury pans that someone but a wider bottom on them for oil capacity.

I just fought with some felpro one piece gaskets and the cast aluminum MerCruiser pans. The thick pan gaskets were too thick I was breaking bolts trying to smash it down, and the thin ones were just a little too thin. I ended up using the thin ones with a good layer of ultra black, tightened the bolts up 50%, let it set up, then tightened the rust of the way. No leaks yet.

i no longer use the one piece gasket for mark 4 engines,i have had several leak and that sucks.when you install the rubbers on the 4 piece gasket make sure to get the rear one pushed all the way down into the rear main cap and always put some sealer in the groove first.i always apply a smear kote of the right stuff on both above and below the gasket.hope this helps.edit in,speedy,don,t use the standard pan gasket on those 572s,fel pro makes a nice one fitted for a stroker pan.

fel pro 1893 is the gasket that is correct for engines with stroker pan.it is a 4 piece gasket.
