Question about 1988 Ford Ranger
I just bought an 88 ford ranger 4x4 4spd od 2.9 . At first it sounded like a sowing machine so my son and I changed the lifters and push rods and found one lifter colapsed. Well after filling it back up with 20w50 oil and adjusting the rockers it sounded nice. Then after warm up I noticed the oil pressure dropped from 40 down to 20 then at idle it goes down to 5. And it has a valve tap. One person tells me it could be a spun bearing another says pump this truck has 170,000 miles. help
I just bought a BII with famous tick..........oil pressure light came on (no gauge). I installed mechanic gauge and showed 5 psi so I decided to replace oil pump. Pulled pan off (not fun!) the pickup tube was clogged and the was part of the timing chain tensioner in pan. I then pulled timing cover off only to find chain streched and the chain guide and tensioner pretty much gone. I think tick was chain slap..........will know for sure in a couple days.

2.9's do that. It could be plugged oil galleys but most likely bearings. worn bearings loose pressure and has a hard time reaching the top end. The oil thins after it warms up.

Possibly clearances "closing" at operating temparature? 20w50? Kinda heavy isn't it?Spun bearing - should make more noise than a "Tap"? I've heard several low and high mileage 2.9 engines "tap" but quits after warm up? That SEEMS to be somewhat common with the2.9 Sorry can't be more specific.
