Oil is not going to the lashers, roller adjusters.

Good afternoon,

This could be a failed oil pump.

I would have a manual oil pressure test done to confirm.

I attached a YouTube video for you of the procedure. It is a major job for someone who has never done it before.

I changed the oil pump, the timing chain guide because it broke and the lashers . Does the timing chain tensioners have anything to do with it? I’m afraid the journals might be clogged have no idea how to unclog them with out having block boiled . Any suggestions would be awesome.

The tensioners are driven by oil pressure.

Are you planning on removing the engine? The possibility of clogged journals being clogged is next to nothing.

I would suggest replacing the engine with either a rebuild or a good used engine.

What other engines will bolt up to the transmission and air right down in the truck?

The 4.6 will bolt up with some modifications but you are better off sticking with the 5.4.
