    How many very new 4 stroke engines will be running trouble free at age 50 to 75 years old ?

    Small block Chevrolets, Fords and Mopars are probably the best designed engines for long life and easy of repair, ever. I also love the AMC designed 4.0 liter six in older Jeeps, I have had one of those for 27 years....

    And the rocker arms themselves are different, the ones you have are for the adjustable system.

    How many very new 4 stroke engines will be running trouble free at age 50 to 75 years old ?

    And the reason why the small block Chevy will still be around? aftermarket support Just like I can still get any part I need for a 4 bbl Quadrajet even though it hasn't been produced in 30 years!

    lifter issue and rock arm registration

    This is right from my OMC shop manual and remember it’s a GM engine whether it’s Merc OMC or Volvo. For your adjustable valve train this is how it’s done and if it doesn’t seem right either the pushrods or lifters are wrong for the engine or something’s wrong with the lifters…and DON’T forget...

    lifter issue and rock arm registration

    If the way I am saying to adjust them does not work, then the only conclusion that I can come to here is that you have either the wrong pushrods, or wrong hydraulic valve lifters for the engine and cylinder heads that you have. That's the adjustable valve train, it should be as I'm saying not...

    with the old style adjustable you have to do the zero lash and either 3/4ths or 1 turn depending on whose spec you are using.

    Alldodge good point on the self locking nuts. All of those should be replaced for the adjustment to hold.

    lifter issue and rock arm registration

    Remember the engine serial # is at the front of the block the casting # is at the rear. It’s also possible that someone put an earlier set of heads on that engine.

    Ahh you definitely have the adjustable valve train on that engine but are following the procedure for the non adjustable valve train or so it seems. Now why you have the adjustment valve train? Well the Romulus engine plant didn’t switch to net lash till 1995 you might have an early engine from...

    If you need it I can scan the procedure out of my OMC shop manual.

    lifter issue and rock arm registration

    And from what I was able to find, of the 2 plants making 4.3s, the Tonawanda NY plant (this is where the industrial and marine engines came from) switched to the net lash system in '92, whereas the Romulus Mi. plant didn't switch till '95, and when the change was made, the base circle was...

    lifter issue and rock arm registration

    OK I don't want to add more confusion here but on these engines besides all the other changes like no balance shaft/balance shaft, and pre-Vortec/Vortec heads, there is also this: adjustable valve train net lash valve train (non adjustable) I'm not sure what year they changed from adjustable to...

    Leak into bilge, bellows?

    Yep I'm not sure where I read that, but it does make sense. The other thing that really helps the older you get is a drive jack to get the height just right, so much easier on your back!

    Leak into bilge, bellows?

    As far as the issue of the O-rings on the driveshaft, grease can get under the o-rings in that groove and keep them from seating, so when I install those, I clean out the grooves and just lube the orings with bit of motor oil, not grease. Grease goes only on the splines.... For lining up the...

    Leak into bilge, bellows?

    crowfoot wrench will work there, some are made to be used with a socket/extension, some have a flex head, all different combinations so you can get to things. I had to be creative to get the lower retaining bolt out on my Cobra's steering actuator, similar problem, the top of the Y pipe was in...

    While I know intellectually I "should" have an outboard here in the salt pond, I just can't bring myself to spend that kind of coin on just an engine! Yes I/Os are a pain here, due to salt water moorage but the repairs are generally simple, can be done by competent DIY guys, and you can even...
