    302 valve seal and gasket replacement

    You need a FoMoCo shop manual then. I had one for my 1970 Torino which had the 302 but that stuff is long gone.

    Channel Lock Stuck In Distributor?

    post up a pic, I'd think about using a very small screwdriver, or a pick.

    302 valve seal and gasket replacement

    5 liter Ford is 302 cu in 5 liter Chevrolet is 305 cu in.....except of course the original Z/28 which was 302 cu in but that will never show up in a boat! So which is it? I don't believe the standard valve train on the 5.0 Ford was adjustable in the same way the older Chevrolets were.

    302 valve seal and gasket replacement

    First of all is this a 5 liter Ford, or Chevrolet they are totally different animals. The older Chevrolets have an adjustable valve train that has to be set right or the valves won't open far enough or close completely either way it will cause problems. There is a 2 step procedure in the shop...

    Internal Coolant Flush and Winterizing VP 4.3 GXI-BF

    Yep it’s hard to give advice when we don’t know exactly what you have. However if it’s the older cast iron version there are 2 plugs on either side of the block, low down not easy to see depends on boat installation. If you do wind up draining the AF remember what I said about bleeding out the...

    Second Happiest Day . . .

    Once you start looking at the price of parts for late model inboard engines you realize the inexpensive inboard alternative does not exist for new boats. Once they price themselves up with outboard parts, why put up with their inherent drawbacks?

    Internal Coolant Flush and Winterizing VP 4.3 GXI-BF

    ALL GM marine engines have block drains, they are simply adapted auto engines. You just have to look for them....on the starboard side, between the starter and engine mount, same place on the port side. Even with a closed cooling system when it comes time to change the antifreeze, there would be...

    Internal Coolant Flush and Winterizing VP 4.3 GXI-BF

    With this job it’s not the draining that’s tricky it’s the refilling & bleeding all the air out. I’d pick up a Lisle radiator funnel kit that makes it much easier to bleed the cooling system. You’ll prob have to run the engine at fast idle 20 min to a half hr to make sure the thermostat opens...

    Compression test results 4.3L V6 2005 what do You think?

    Lol this depends on age and orthopedic difficulty if you’re old enough for Medicare use the bolts! the V6 manifolds aren’t that bad the V8 ones are probably 45 lbs each. V6 manifold gaskets are not slotted but you could just cut a slot.

    Compression test results 4.3L V6 2005 what do You think?

    Well you’ll need: A pair of manifold to cyl head gaskets (regular automotive Chevy 4.3 ones are fine) Merc OE manifold to elbow gaskets Razor scraper to scrape off old gaskets Mill bastard file to clean up sealing surfaces if reusing the manifolds & elbows. Now if you’re in freshwater you may be...

    Compression test results 4.3L V6 2005 what do You think?

    Question: When you did the comp test was the engine warmed up and throttle valve all the way open? If not the results might not be as accurate as they could be. Also, I’m not convinced that the difference you saw is really enough to be concerned about on a 16 year old engine. I would definitely...

    4.3 OMC Cobra and or...

    I know people focus on top speed but the closer your WOT rpm gets to the actual redline the less strain on the engine every time it pulls the boat up on plane. Like a trailer tow gear ratio for your truck. My boat I feel is on the big side for a 4.3, 20’9’.

    4.3 OMC Cobra and or...

    Normal redline is 5,000. I had mine out in the bay today and it easily pulled 5,000. This is with a 15.5x15 prop. It limits my top speed but reduces the strain on my old 4.3. Fake cat is to keep birds from turning it into their bathroom.

    Compression test results 4.3L V6 2005 what do You think?

    If perhaps water is getting to that cyl from a leaky exhaust manifold to elbow gasket the exhaust valve in that cyl might not be sealing 100% due to rust. Might want to do a leak down test. If it shows leakage past the valves esp the exhaust valve I’d remove the exhaust manifold to take a look...

    97 four winns motor replacement

    It depends on if the 97 is a Vortec engine which has different cyl heads and different intake manifold (8 bolts to hold it down vs 12 for the pre Vortec). You have to check what you have. The 94 for sure is not a Vortec. It might be possible to use the cyl heads from the 97 on the 94 block if...

    1987 5.7 omc outdrive

    taking that apart is like taking apart an automotive differential, you have be able to set preloads and rolling torque, there's more to it than you might think. Unless you have to tools and experience you might end up with another blown up drive. there are vids on a few sites that show what's...

    Power Steering Pump Test

    interesting I wondered if you can test a power steering/actuator & cylinder while off the boat? the old style ones with the seperate control valve and cylinder, can be rebuilt apparently because the same units were used in US cars back in the 60s and 70s, people are still using these on classic...
