Hi all!
This isn't specific to the LUV truck, but rather an issue I'm having on my Isuzu Bellett 1800GT equipped with the G180SS engine. Near as I can tell, it's identical to the single cam, counter-flow G180S used in the early LUV pickups with the exception of the twin-SU carb setup and higher compression pistons.
At any rate, I get a massive amount of clatter on startup until the engine builds oil pressure. It lasts about 2 seconds on cold startup and you get just a hint of it on warm startup. I'm having a hard time discerning whether it's specifically valve noise or rather chain noise due to a lack of pressure in the chain tensioner. I would like to think that chain noise would be much quieter, but I figured it would be best to ask if anyone has had any similar experiences with this motor.
Any help at all is greatly appreciated!
