Engine knocking/clanking when accelerating hard, and excessive blowby in air filter?
Just got my 1988 YJ w/ 4.2l manual back in July of last year, and am working on starting to get it trail ready. Ever since I've gotten it I've had two issues though.
First: When accelerating hard/going up hills, there is a clanking noise and I don't seem to have much power. It doesn't sound like any piston knocking noise I've heard before, more like a loose bolt vibrating or something. I've checked all the bolts I can think of, and everything looks nice and tight, but the noise persists. It's quite noticeable when I'm on the highway, and is very annoying. I mainly just wanna see if it's something that could be evidence of a deeper issue with the engine/transmission.
Second: Ever since I got the Jeep I've been slowly noticing a blowby issue where oil is getting blown back into the air filter. It got so bad once that I practically lost all my oil into the air filter pan and ruined the filter. Ever since then I still seem to have some blowby coming back into that pan, nothing as bad, but still definitely there. Any ideas on what I can do to fix that?
Thanks for reading and in advance for any help! I've been on the forum for a while but it's my first post. Excited to get involved in the Jeep community!
