Neverdone
He's not done yet...
So having car troubles again....... poor old black betty, my truck a 96 Z71 with a 305. I suspect she is getting ready for the final round up.
She has 174,000 miles, 74,000 miles I put on myself over the course of the last 8 years. By the way that is all on the original motor, trans, axles, bearings, drive shafts, u-joints, everything. And she hasn't lived an easy life for a half ton. She has spent a lot of time dragging a trailer with my jeep on it and other things..... Put on a dual straight pipe exhaust many moons ago, K&N cold air intake, throttle body spacer, and an aux 10,000# trans cooler. Other than that she is stock.
Couple days ago I took off from a buddies house and she sounded pretty rattly.... ...... Only a couple times taking off from a stop sign.
Drove it to work last couple days. When it is cold as in not ran for a few hours and you start it up it sounds fine idling. But when you take off it sounds rattly again . Also it has high oil pressure. Normal for the truck when the motor is cool is 60psi running warmed up 40psi running. Idle it sits around 40 psi cool and 20psi warm. This morning it had about 70psi when I pulled out of the driveway under acceleration then backed off to 60 psi. 5 miles down the road I stopped at a stop sign and everything was normal.
My personal experience tells me it is not a rod knock just because of the fact that it doesn't do it all the time, but the fact that the oil pressure is a little high makes me think there is a bearing walking around [S.
My only other thought is that it is a piston slap but I am not sure.
I do know that the catalytic converter is on its way out. That has been dancing around for quite some time (really annoying sounding). Thinking I am going to cut the cat off and put up a test pipe just to be sure that is not it. But after that, don't know. She has fresh oil 800 miles ago, pulled the stick yesterday and it is full and actually looked pretty clean for having that much time on it.
Anybody else have any thoughts?
I would hate to see old betty go, but sometimes you just have to let them....
