I would go ahead and pull both heads and have them cleaned up and have new valve springs and seals replaced. The cost for both of mine was like $300. Have them make sure that the heads are flat so that the gasket won't blow again. You'll likely spend $100 for the new gaskets as well. I use Felpro marine gaskets. I couldn't find marine valve cover gaskets, so I used the rubber automotive style.

If I'm pulling the top end apart should I go ahead and do both sides? What about the heads, should I take them in to a shop and have them checked out? What is the approximate cost for resurfacing etc.?

My vote is for a blown head gasket on the port side between 5 & 6.

I did a compression test on my PCM 351 and the results are as follows:
1=118 2=125 3=130 4=140 5=82 6=58 7=125 8=138 I drained the oil and there was a coulple tablespoons (approximately) of water that came out when I first pulled the drain plug. Any help on a diagnosis would be appreciated. Thanks. |
