Pushed my motor too hard and starved the bearings. Upon starting to pull it apart the piston connecting rod where it wraps around the crank i can move a few mm’s…which explains the knocking sound. The pan was filled with metal filings from that bearing which just doesnt exist anymore. As of now i know the bearings will all be replaced on the bottom end and clean out the internals of the filings. Does my crank more than likley need work done to it?I havnt seen wether or not theres major gouges in it… or replace the piston connecting rod?
My plan is to make this motor which was already in great shape run superb again and be able to throw my bolt ons onto this guy when my current SR starts to get weak or blows one day.
The motor ran smooth as butter and had great compression accross all four. This was the 1st SR motor i had…Id like to build it up…my goals nothing crazy…like tops tops tops 400whp…even then my goals 300-350rwhp tops.
I was debating just doing the bottom end which is what o was asking how much it would run me for the damage ive done…Or…i could continue to take it apart and just do it up to the tits with pistons, connecting rods, cams, knife edge the crank, HG etc etc…I just dont like seing the motor sitting there…its a project awaiting to be re-born. I see buying a perfectly working longblock to rip apart pointless…Id rather do a OEM bottom end rebuild and know that i have a fresh bottom end that was lubricated and taken care of from the begining.
Get the crank ground and polished and get all 4 journals done, then order the next size smaller rod bearings. Depending on the condition of the bearing journal on the rod, you might have to replace the #3 rod.
If your at that stage, you should plasigauge the main bearings in the block to see if an entire bearing kit should be ordered. If there is anything more than that, you’re probably looking at an entire build.
If the oil was starved from the bottom of the engine, think of how dry the top has been.
Thats the plan in a year or so i geusse. I was just bored and started to take it apart to see what happened…ive got other things that i need to save and invest in.
Guys this was my old motor…I may not be touching this motor again for months or up to a year.
