Spun bearing

Hi

During a routing drive to the office tonight, my recently new to me late '99 7.3 spun a bearing.

It was surprising although there had been recent indications something was amiss such as smoking heavily on first starts last two weeks; there were several incidents of hiccups in recent days although it was momentary and she seemed to come out of it.

How about Blackwater long blocks?

Hi

My gut mostly tells me. The knock happened on a deceleration on a city street. The knock is low and quite audible through the oil pan area.

any shiny speckles floating in the oil on your dipstick?

but diagnosis aside. If your not skilled at rebuilding engines depending how bad the knock is and how bad its running if a long block is within your price range id do that

is the idle terrible? a bent pushrod would cause noise from it rubbing the bore wall and depending how bad it is can keep an intake or exhaust valve from opening

Hi

Because of the terrible "cold -hard start" condition I bought it with from ebay..i think she was an ether baby.

I am looking at possibly a Blackwater long block. the price seems good and is only slightly more than a used engine.

I am somewhat paranoid about yard engines saying only this much miles... no way of telling and no yards near here have one. Too much risk to save only $600 over Blackwater.

Any suggestions for a longblock vender ?

heres what black water offers.

Our remanufactured FordŽ 7.3 Powerstroke™ Diesel long blocks are assembled using Mahle Pistons, Mahle Piston Rings, Clevite Bearings, Melling Oil Pump, SBI International Valvetrain Products. Johnson Lifters, Felpro gaskets, OEM Camshaft & Timing Components and Pioneer Freeze Plugs.

Gasket set does not include valve cover gaskets, front cover gasket, sealing rings for the high pressure oil system. Get these from the dealer or aftermarket. Make sure the front cover gasket is correct.


spending the extra 600 on a brand new engine is better than a used engine with possible problems

Hi

Idle sounds fine except for the knock. I crawled under the truck and definitely low and deep...

I was going to do injectors and up pipes so I guess now is the time as pipes will never be easier than now.

hmm pull your dipstick and shine a flashlight on the oil (if you do it when its dark outside) check for shiny specs. this can tell alot of things
