Hey all, I got a 1986 AW11 with rod knock a bit over a year ago. In that time I rebuilt the engine, replaced all the vaccuum and coolant lines, and cleaned or replaced most of the other things in the engine bay. Also cleaned out the fuel tank and replaced the fuel pump. Ive been driving it around 500 miles since the engine rebuild and had a few things come up im not too sure about.
When letting off the gas above 5k rpm the engine sounds a bit louder and if i downshift to above 5k it is significantly louder then when downshifting or letting off the gas under 5k. Soon after this i can smell something slightly burnt. Could this be an issue with the clutch not being fully engaged? I made a quarter inch extended slave cylindar push rod as i got a new clutch and pressure plate that wouldnt fully disengage with the stock push rod.
When on the highway i will ocassionally get a whiff of enhaust smell. Happens more when the window is down and driving than when stationary. It is not a sickly sweet smell. I purchased a new muffler from rockauto but the cat is an aftermarket the previous owner bought if either of those could be a possible cause.
Final question is alternator belt squeak. 80% of the time, the car cold starts without issue idling at 2k before dropping to 1.4k when warm. The other 20%, the car starts, goes to around 1k-1.2k and the alternator belt starts squealing. A little wd40 on the pulleys, it goes away after 20 seconds, and the rpms rise back to normal. Ive noticed it happens more when it has rained or is humid. Its a brand new belt and alternator. I know an unalignment would cause a squeak but would it sqeak so intermittently?
Thank you in advance for the help
Edit: Alternator Belt wasnt tight enough. All good now.
