Engine Noise (Videos Included)

Hi guys, i've been bugging everyone about my engine noise. not the fast clicking one that i believe is the ALB, this is the one coming from my Timing Belt Area. all my friend mechanics i've asked just tell me that it's big trouble and to sell the car. i don't want to though. take a look and tell me what you think. like is said before though as it warms up and drops in oil PSI it gets quieter. all help is greatly appreciated guys. thanks!



here is an update of my engine noise, This is after 210 miles on 10w40 with MMO, if you guys can try compare the 2 and post any other suggestions besides a engine swap, rebuild etc. thanks! they still sound similar but in real life it is a night and day difference! thanks!

thanks guys! hope i can get this fixed. don't know if it's lifters or what.

if it's coming from the timing belt cover I'd say the tensioner is bad. I hope you aren't driving like that cause once it fails that means BENT valves!!!

it can't be those, though. like i posted before i got the car at 149,367 broken water pump. changed pump, Timing Belt and Tensioner and am only at 150,121 miles now. you think it could be a faulty tensioner or pump? do you guys suggest changing all 3 again? it is my daily driver. i use it to commute to work and home. it had that noise before with the broken pump when i first got it.

Hmm, try removing the A/C compressor belt and see if it stops making that noise.

gorgot to add what I have tried....

i've ran the car without PS, AC, ALT belts for a few minutes to see, still had noise. I used 5w-30 with lucas, went quiet at running temp. tried 10w-40 synth blend was louder. added MMO went quiet at running temp with low oil PSI. that's why I was thinking if I used lighter oil it'd be quieter. any other suggestions?

If the noise stops when using lighter oil your oil pump is failing. I know one thing for sure , low oil pressure is like cancer, that engine is dieing if you don't get this under control ASAP!

I installed a mechanical oil pressure gauge and when I was running 5w30 with lucas when I start the car for about the first 10 minutes it was at about 60 psi, then when running warm it was at 15-20. with the 10w-40 and MMO at start its about 60 for ten minutes then at running temp it was about 10-15 and running quiet. I think my oil psi is a little below average . that's why I was thinking of running thinner oil to keep the engine quieter. if it runs quiet on low pressure and thinner oil i'm guessing it must have some internal wear, any other suggestions to fixing the noise? if running thinner oil isn't a good idea what else do you guys think I should do?

If it was my car I'd get a low mileage engine.

that is my future plan. but for the next 2 years I won't have the money, the time, or the place. I rent an aprtment and don't think I can do the engine swap in my parking stall, although I did my timing belt and other things. its too big of a job for my stall. plus shipping for the engine would be outrageous right now.

super hard to find locally bro, I live in Hawaii. all the G1 legends here are being sold with the whole car with jus about as much mileage as mine, junk yards have junk engines. the reason ima be busy is ima be in school which is 7am-2pm mon-fri for my A&P license and I also work full time to pay dem bills. I guess I could just start savin up and try to order my engine and swap it during my school breaks, like xmas or summer or whatever. its pricey and sounds crazy to do this.. not many would go through the trouble but I think its worth it. nothing like a G1 legend. they're becoming harder and harder to find now days, if it'll last me til I fiish school i'll definitely ship it to the mainland when I plan to move out there and do my swap there. but until then is there anything else I could do that may avoid being stranded and doing the swap so soon?

Hmm, jack up the passenger side, remove the wheel and remove the splash guard that covers the crank pulley. I think you'll get a better sound in that are than trying to hear it from the top.

i've also done that. it was still pretty hard to find the exact spot. I just know for sure its in the timing belt area, you think it could be the crank pulley not on good? I torqued it to 117 ft lbs. or possibly the crank shaft or something?

To be honest you need to take your car to a mechanic, all this guessing is doing you no good. I/ we would love to help but without physiclly observing the car it's all speculation.
