Appreciate the bolt tip, I am not one to force things and break them, but I’ll use the strap wrench. Thanks for fault finding tips too, I’ll try them all to be sure before I pull the engine out, but I’m doing my research early on strong evidence.
I myself haven’t confirmed a cracked block...
Great, thanks for the sizing info.
Thanks for tip on crank bolt - I’ll avoid that, but can you tell me specifically why? Just that I’ve seen engine guys over here use a big 3/4” ratchet to turn the crank pulley to rotate and work lube in cylinders prior to firing up an engine laid up for years...
Thanks. If block is cracked and I go long block plus manifolds, I am assuming the rest of the engine will swap over ok, if I buy the right block? Any company in particular to look to get a block from?
I’ll replace anything that doesn’t look reliable, eg hoses and wiring as required - is there...
Yes, I’m heading out this weekend to check:
fuel supply to carb, Fuel pump pressure, carb working ok and run with new fuel off a portable tank
plus
spark at plugs, new plugs if required
Compression
I’ll change oil prior to this and replace fuel filter too.
I’ll definitely use a machine shop for testing and machining, plus advice.
But if I go new block and keep the 4.3 I’ll be doing almost everything myself unless totally impossible without serious/specific tools and machines.
I’ll have to buy some kit/tools but I’ll save that cash in paying other...
Thanks, great info, appreciate the detailed reply!
I’m not overly worried about top end speed/power,
So a 4.3 might be the easiest. I can move mounts and do Fibreglass work, so if I have the space I guess 5.0 will be more popular when I eventually sell it after I’m done with it...
Thanks, and thanks for the quick reply!
Of course, before trashing it I am going to test fuel/spark and work backwards so I can run it or recreate the failure the seller said he had. I have the ability to do that no problem.
The specifics of these engines however and the costs of parts, I am...
Hi, I think this is quite a specific ask - sorry if it's been answered before, and thanks in advance for any help or comments, no matter how blunt...
I Just bought a 1996 caravelle with Merc' 4.3 and alpha one, with a dud engine but decent drive and good hull.
Seller said it was cranking and...
