    Default What to look for, pulling the pan off a PCM 454

    Just bought a used late 80's vintage Supra with the PCM 454 330hp. I'm switching the drive train from typical tourny boat inboard to a v drive set up using a BW 72C with BW direct bolt up V drive so that I can use the existing shaft location/strut etc. I have also purchased a V drive oil pan from a member here on the forum. Along with swapping out the pan, is there anything else I should do while I have the pan off the engine. Hour meter shows 315hr and engine seems to run just fine.

    thanks!

    You didn't mention it and most here would consider it common sense, but I'll put it out there just in case... You're going to have to get an oil pick-up to go with your new oil pan. Given the relatively small cost, I'd consider a new oil pump too and have the pick-up brazed on. I've read in a quite a few threads, depending on the pick-up, you may want to add extra supports to it. I haven't any fist hand know how in this arena, but I'm sure you can find someone here to point you in the right direction.

    What pan did you buy?

    Sounds like a cool project. Are you putting the v-drive in to throw a better wake for wake boarding? I'd think if you could get the bow out of the water a bit, you'd pick up some fuel efficiency and top end speed too.

    make sure it has 8 connecting rods. all bolted to the crankshaft and pistons on the other end that should about do it. ( cast pistons, 3/8 rod bolts and cast crank thats a sweatheart. )

    Ok, smart A$$$, I'll check to make sure all 8 rods are present and accounted for

    I was just wondering if standard operating procedure would be to check rod/main bearings while it was flipped over or just assume all is good with an acceptable oil pressure reading.

    I did buy a Dooley pan, windage tray and pickup.

    And yes, looking for a better wakeboarding/surfing wake along with more seating options. I'll be adding a hyd trim plate also in hopes that I won't need much if any ballast up front to balance the boat out.

    As long as you have a torque wrench, I would definitely take the time to look while you are there, can't hurt. Based on what I have seen in other engines, I would look at each rod and main, rather than just a couple. It's easy now, not so easy once the engine is in the boat, and basically costs nothing unless you decide to change some or all of the bearings.

    You can also take a good look at what's in the pan besides oil, if anything,, and even the bottoms of the cylinder bores while you are looking?

    I agree, Never hurt to put a set of bearing in it.
