    Volvo Penta V6-240 Fuel High Pressure Dropping to Zero

    I don't have Diacom (so can't read the .rec files) and I'm not familiar with this particular engine. I'm not even fully versed with exactly how some direct injection engine fuel systems work with their multi-pressure stage fuel systems. I do know that on some direct injection engines there is...

    F150 Injector stuck open

    If an injector has been stuck open fuel may have got into the engine oil, in which case it would obviously be a good idea to change the oil. I too find it surprising some mechanical and electrical things last as long as they do. Injectors usually last around a billion cycles on a vehicle, but...

    Volvo Penta V6-240 Fuel High Pressure Dropping to Zero

    I've never used OBD equipment on a marine engine but I diagnose vehicle engine problems everyday. On a car P0174 would point to lean mixture on bank2, on this boat engine the 0174 code also seems to point to lean mixture on bank2. The way it detects mixture is using an O2 sensor, the boat engine...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Thanks, I don't know what/if a different circulating water pump is available that has a barb though I would think there would be something available. Still I'd prefer not to have to fit a different water pump, so if I were to fit a heater matrix I'd prefer to go with the 2 barbs method. I didn't...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    What would be the usual way of plumbing in an oil to raw water heat exchanger / cooler? Also along similar lines - of plumbing in a heater matrix on a raw water cooled engine? I was thinking if the 'main' engine hose (the widest diameter water pump to thermostat housing hose) which carries...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    My '96 Ford 302 has hydraulic flat tappets / followers, the 'same' engine in a car or truck would have a roller cam. I've never used a zinc additive but have read modern oils are low in zinc and that's bad for the cam. Even the 'classic' 20/50 mineral oil and straight 30 oil I've used doesn't...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Is that fully or semi synthetic? I think I used to see a much wider range of oils than seem to be available now. These days it seems most stuff is 0/30, 5/30 synthetic, even some 10/40 semi is labelled as 'classic', then there's the really old stuff like 20/50 mineral and straight 30 or 40...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    I agree, I ran it with 20/50 last year and oil pressure after a hard run was higher than with the straight 30, even when I only had 4 / 4.5 quarts in it in both cases. But with more of the 20/50 in pressure seems to stay higher after a hard run than it did with the smaller amount of 20/50 last...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Thanks Lou, Since realising the dimples on my stick are where oil level should come to if I put in the quantity that's correct according to the manual I'm happy just filling to the dimples. As you know, the engine is relatively newly rebuilt, it doesn't seem to use or lose any oil between...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    We're both in the same situation, oil level reads well above full on the stick when we put the correct amount of oil in according to the manual. We both kind of second guessed the amount of oil we should put in and aimed for a compromise quantity, less than the manual says but still above the...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    It has just occurred to me that when I was rebuilding the engine I wasn't sure whether the outer housing / tube was supposed to be fitted so it runs down the port side of the engine then bends to run under the pan before bending again to connect to the starboard side of the pan, or supposed to...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Thanks Lou. That's effectively what I've done. I was using the term hash marks but it's got 'add' and 'safe' lines (not hash marks) in addition to the dimples. Is my dipstick different to other 3850474 dipsticks? Do they usually have the add and safe areas / in the same position as mine? Do...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    My engine does have the oil extraction / dipstick tube. It goes down the port side of the engine, completely around the back of / under the oil pan and enters the sump through what would be the drain plug hole on the starboard side of the pan. I posted a picture of the engine above. So it seems...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    I still haven't totally confirmed it's the correct dipstick for this engine but a quick Google of the part number shows it is an OMC Cobra stick. I hadn't posted pics of the stick when you posted but I don't think it looks like a bad stamping, though it would be easy for a DIYer to stamp the...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Dipstick pic showing the 'safe' area and the 2 dimples. The oil is up to (down to in the pic but you know what I mean) halfway between the dimples, which is way above the 'safe' area. It's way above the safe area if I only put 4 quarts/litres in but it's between the dimples with 6 litres in. You...

    Ford 302 engine oil dipstick - 1995 OMC Cobra, Ford 302, VolvoSX

    Thanks, yes I'll check the part number when I get around to taking and posting a pic of the dipstick. The pic will show what I mean re the hashed area and dimples. One thing that got me second guessing was the oil pan looked in great condition and I knew the engine had been rebuilt before.. I...

    Thanks for the replies. I'll come back to this thread and post a pic of the dipstick. I don't think I'm the first to encounter this, I watched a Michael Romer YouTube vid in which he changes the engine oil on a Ford engine'd OMC Cobra setup, in the comments section someone else said they put...
