Re: knock sound
If you've been running with a leaking oil cooler it could be one or all of your engines bearings. Whatever you saved on the purchase you're gonna blow on a rebuild or engine swap. You may as well part it out.
man u need to re-write your question! i dont know where u came from but first of all u need to make sure u write it right, that people can understand u and give u the right answer for the right question. Im from Ukraine live in the states for 4 years already, personalty think my posts people can understand with no problem! so now can u tell me exactly what the problem is ?
whats mean " wether getting on gas or off" u mean "weather" ?
whats mean your "1g"
Come one lets help each other, to understand batter here on the forum, thats what that forum was mad for
Oil pressure is around 70. If you are sitting in the yard and rev it up to 1,000 rpm it makes a bad knock sound. sounds kinda like you putting a card in a bycicle wheel. But if you rev up past 1,000 rpm it goes away. As soon as you get off the pedal it will make that sound around 1,000 again and sometimes while its idleing at 500 rpm.
ask your friend to help u , let him seat and hold rpm until that noise come back, u look for that noise if it really coming from pass. side like u saind thats main bearing. i would say that could be valve stuck , lifter or timig belt 1 tooth got loose
