What would cause a flooded LT1?

[jderry]

Did a compression test

I did it for six cranks TB open
196,197,198,200
199,198,199,197
These sound good for my cam and compression ratio?

[SOPES]

Well it sounds right, the best thing about those numbers is they are all close !

I was looking at some venom injectors a while back on amazon

[jderry]

Bad news, put oil in it and it sounds like I have a knock.

Fluctuating oil pressure? And the obvious checking the oil? Sounds like you ate some rod bearings

[jderry]

Oil pressure is great 50 psi at idle.
I feel like the gas probably washed away some oil and starved the bearings.
I pulled the pan, the front two rods have a lot more play the back six to.
I am about to go pull them out and take a look. I checked the back four cylinders and the bearings looked a little worn, but still had life left.
I am thankful they were not spun to stuck to the crank.


Say the front two rods were starved some and are very worn, is it safe to do just the rod bearings?
I would feel better doing mains too, but that's a pull it out type project.

[jderry]

Cylinder two spun the bearing. Not sure if the crank is useable yet.
Going to have my dad take a look after he gets home from work.
Not looking good so far.

Bummer - very sorry to hear

[mcalus]

Sucks to hear :/
Were you running a stock shortblock?

[jderry]

Bottom end was all stock.
Engine is on the ground now.

No use crying over spilled milk. Throw some bearings in it and get it going again this weekend

[JoeliusZ28]

Sucks, im surprised you went from running great to blown out bearings in a single pass though, that just doesnt sound right.

[meissen]

They always say they run best right before they blow up.

Seriously though, the oil was probably saturated in gas for longer than you realized due to the leaking/open injector.

[jderry]

I am sure it was. I doubt it went bad all at once. Probably just finally stuck wide open and poured.
When I cranked it over with the bad injector in and no plugs, it was spewing probably a few oz per revolution.
My car holds about 5.5-6 qrts of oil with the big K&N filter I use.
When I drained it there was 8 qrts. I checked oil before driving to the track and it was right at full.
I got a 10/10 or better crank and Clevite bearings on the way.
Since I dropped the k, I am going to do my QA1s and maybe LS1 brakes now too.
