Spun bearing
Apparently a common issue in the LSA world. But it’s part of the game I guess. Currently sitting at 703 whp. bolt on +e85 car. No cam, heads or internal work. Hopefully I can salvage block. I’m sure crank and bearings of course will need to be replaced. Any suggestions on upgraded bearings? Buddy of mine uses “king” brand bearings I believe. If block, crank and bearing are all trash. I’ll prob be in the market for a new short block or stroker. Any advice is welcomed!
I’ll be letting an engine shop put it all back together. And I’ll throw motor back in. I’ll also be upgrading to the melling 10355 HV oil pump, SS3 GPI cam while it’s out. I was using 5w30 oil at the time of it spinning. I’ll be upgrading to 20-50 VR1 oil as well. Once motor is back in the car. Will I need HV oil pump if I switch to VR1? I got a few LSA buddies running factory pumps with 850+ . Any other suggestions?

Dang, that sucks! You'll be back stronger than ever though! Mine is making quite a bit more power than that on the stock oil pump and stock bottom end, and the oil pressure is holding steady at 30psi hot with Mobil 1 5w30... But who knows for how long?

How did you catch it? Low oil pressure? Just want to know what to look for.

My LSA build worked out great! GPI and I discussed it and I’m beyond pleased. Talk to Aaron — he’ll help you spec a good one...

Fingers crossed. Part of the game tho. Luckily I got a daily to drive. And it’s winter when it broke. Not mid summer. Looking for the bright side lol Quote:
Yeah GPI is literally 2 miles from my house. I been in touch with Ryan & Ben. I’ve had people tell me it could be a number of things (in the tune, too much dome pressure, or failing oil pump, the fact I was using 5w30 M1 with my power level, just normal LSA issues, and blocked pickup tube) guess we will find out.

The factory oil pans aren't the greatest for hard acceleration. We suspect it as being a factor in our last failure.

Man, that just sucks. Sorry to hear it! Hopefully it's not too much carnage and most stuff will be salvageable with any luck. In any case, good excuse to build it back stronger. Best wishes, dude!

I was just watching a video of a guy explaining how ls blocks should have a larger oil pan especially with a higher volume oil pump.

Care to explain why? I never really understood pan volume in comparison to a HV oil pump. If the pump is flowing more sufficiently then what’s the need for a bigger pan? Just curious.

I've heard of guys cracking the block going over 1000 hp, supercharger rattle, burned up piston from too much boost, collapsed bricks and rocker/trunion issues but this is the first spun bearing I've read about. I wouldnt say it's common. Lots of guys run 5w-30 with zero issues so I'm wondering if you had a one-off bad oil pump or something.

It's not about the pump. More about returning oil to the pan. Gravity can only do so much. There's also a difference between high pressure and high volume pumps.You need to ensure that theres enough oil in the pan to pump baseed onthe flow from the pump and return to the pan. During higher RPM operation theres lots of oil up top from pumping and windage.
