bearings for 351W
I'v got a 1988 f150 4x4 351W EFI that has low oil pressure. when I bought it, the pump screen was plugged 90% and the previous owner had driven it that way for 3 MONTHS OR MORE!
I got a good deal on the truck, so I had the pump and screen replaced and had my mech check the bearings, he said that they were so-so (his words).
Oil pressure is better, but once it gets warmed up the pressure at Idle is about 2-5 psi. I know, not good. I think the bearings are worn from the previous owner. The whole truck has only 79K miles on it.
So, my questions are : Can I have my mech replace just the rod and main bearings? Will It last 80K more miles? can I have him use bearings that are .001 thicker?
My mech is very proficent, but somtimes uses parts that are only mediocore. He can also do the bearings with the engine in the truck which saves me alot of money.
Any problems doing it this way?
Thanks in advance.

To use the next size bearings will require the crank to be removed and machined. There is no way it could have worn that much. Actually chances are that the crank hasn't worn much. Putting in standard size bearings is a reasonable cheap fix.

Thanks for your reply,
I didn't realize that you have to have machine work to use bigger bearings. Also I suppose the crank has not worn that much, since the bearings are softer than the crank.
Thanks again.

You can even do the bearings yourself if you wanted too. Not much to it really. Just a matter of taking your time and having a TQ wrench. I did mine in my truck lat year and it only took 4 hours start to finish. I paid less them $100 for everything.

Qoute 'It's better to ask for forgiveness then to ask for permission. '
The actual qoute is ' Its easier to ask forgiveness than to ask for permission'
Are you married w/children? If not, Just wait, you'll see what I mean!
ANYWAY, My truck is a 4X4, which make getting the pan off a PITA. My time is worth the extra $200 to get it done at my mech. $307 is what it would cost for him to pull the pan and replace all mains and rod bearings. Better than I could do!
