I finally finished getting my 89' GL together after an engine swap and a bunch of rehab, put around a 1000miles on her, and started to hear a sound from the motor. Its not audible from the cabin, only when your standing over the motor and revving. I suspect that one of the rod bearings is just starting to go out, but before I begin to rip her apart (again) I wanted to see what someone who had delt with this thinks.
A little background - recently swapped the oil pump, timing belt/tensioner, adjusted all the valve clearances, and replaced the head gasket with a new, MLS one. I checked my oil pressure, and it running in a normal range. I would describe the noise as more of a fast, rapping sound as opposed to a knock at this point, so I would suspect its still very early stages. There is NO sign of the sound at any RPM until the motor is FULLY warm, then above around 2200RPM, the sound starts. The noise increases with engine RPM. Now, I know that the oil pump chain tensioner can wear out, and create free play in the chain, is there any chance that this is the problem, not a rod knock? I don't know how that would sound, or if it would even make a sound. Any input would be very welcomed!! Here is a link where i'm running the engine, the sound can be tough to hear in the video, but its only at higher RPM like I said.
Drop the pan, check the bearings, from the bottom. This can be done in about 1-2 hours depending on skill and equipment. You may be able to get by with new bearings, but beg, borrow, buy a micrometer to make sure the crank is round. Don't just plastigauge it. I tried that too many times to only have to pull and grind the crank.
However your sound is not too horrific yet, so you might get lucky.
justytrudeau: Just replaced my headlights with LED's as well as all my dashboard instrument cluster. None of them work, and now my taillights have gone out too. Likely wiring issue, eh?

91justy4wdshea: Just got a Justy for $100, did a lot of research about the issue, which was just one day it just stopped moving although started and ran fine. I then discovered it was driving just only in 4wd. I think I need new hubs. Anyone got any for sale.

Arch: Anyone know where I can get a left front cv axle for a 1987 Justy? The only ones I can find (don’t ask me how I know) are for the later equal length years. I have scoured the ‘net for it, none available. Thanks in advance.
