    When do you replace the bellows? '01 Alpha One Gen 2

    Get a bright LED flashlight, tilt it all the way up & look for cracks in the rubber. You’ll probably see a lot of tiny cracks in the folds of the bellows which means it’s past its service life. I have gotten about 10 years out of each one before I see that happening. If you replace use OEM parts...

    Omc 4.3l won’t stay running after 60 sec

    Something isn’t right here. If it’s a 1992 it came with a mechanical pump. If it has an electric pump then somone converted it. If that’s the case it’s probably an aftermarket set up. In either case you have to rig up a pressure gauge to find out what’s happening. If the pump is bad changing the...

    1992 4.3 might be the last year of the mechanical fuel pump…

    Showing my Tri-axle Trailer some TLC . . .

    I’m thinking that they may have gone with the hoses to avoid corrosion with steel brake lines although the stainless steel lines I installed in 2004 still look like new!

    How do I Remove Very stuck on Exhaust Manifold Gaskets?

    That’s good the cyl head gasket isn’t as fussy for sealing as the manifold to elbow gasket

    How do I Remove Very stuck on Exhaust Manifold Gaskets?

    Or a 50/50 mix of ATF & acetone.

    How do I Remove Very stuck on Exhaust Manifold Gaskets?

    Maybe heat it with a heat gun carefully…I had a heck of a time getting the old gasket material off. Took quite a while!

    Upgrade to 4bbl, what about throttle cable bracket?

    As for my 4160 I’m still wondering if those loose clutch bolts on the secondary metering plate were the source of my troubles! I might just have to try it. It was a shame because I was able to source every single part needed to make it fit perfect on the OMC 4.3; accel lever adapter, OEM fuel...

    Upgrade to 4bbl, what about throttle cable bracket?

    And let’s keep in mind about the Qjet Unlike Holley these were OEM on literally millions of GM vehicles starting in 1966. Yes GM did use Holley on there higher performance models but that was a drop in the bucket. They spanned the range from the short lived Pontiac OHC in-line six to the 454...

    Upgrade to 4bbl, what about throttle cable bracket?

    I finally got my act together and put together a fuel pressure checking set up like what was shown in the information on checking your boat's fuel system with the pressure/vacuum gauge, hoses, and all the fittings, what was the most headache was getting the right fittings to mate with the male...

    Upgrade to 4bbl, what about throttle cable bracket?

    Agreed I think that explains the variety of experiences/opinions as much as herd mentality lol.

    Showing my Tri-axle Trailer some TLC . . .

    Ted they make special tools for removing & installing those dust caps that work well! I finally bought them after years of improvisation! About the rotors yep that’s what I see here too only stainless seem to last.

    Upgrade to 4bbl, what about throttle cable bracket?

    I tried a brand new 4160 on my 4.3 about 8 years ago (the one Holley says is calibrated for the 4.3 that they still sell for about a grand) and it never ran right despite trying all the tricks that Holley techs advised and everything I read about Holleys running too rich which is what this one...

    Yep haven’t had to do one of those yet but I’m ready (Autel MX 808 bi directional scanner).

    Engine stalling when you give it too much throttle on take off

    Ever look inside the fuel tank via the fuel tank float hole to see if there's crud in the tank? What about the pick up tube and anti siphon valve? I also for sure would get a hold of an advance timing light and make sure the spark is advancing as it should. Honestly I'd rather have a simple...

    Volvo AQ 260A lost compression, water in valve cover

    Agreed, they can check for cracks as well and evaluate overall condition.

    Volvo AQ 260A lost compression, water in valve cover

    I find it interesting that your plugs are bleached white, but the pistons all seem to have a fair amount of carbon on them. Looking closely it's hard to see where the HGs blew but it is often between the middle cyls beause that area runs hot seeing as how the exhaust valves are right next to...

    Volvo AQ 260A lost compression, water in valve cover

    milky oil shows up sooner under the valve covers than it does on the dipstick, it is thicker than just motor oil alone so it may not travel up the dipstick tube as quickly as it shows up under the valve covers.

    Volvo AQ 260A lost compression, water in valve cover

    I had a similar problem about 10 years ago, both head gaskets started leaking after an overheat that happened about 2 seasons earlier. Symptoms were water in the oil, rough running when cold, reluctance to start when cold. Compression testing was normal but I had some water in #2 and a tiny bit...
