chevy oil filter by pass
is there a chance of oil starving of the crank when on cold start with 20-50 and oil filter bypass plugged on a chevy small block? is plugging the filter by pass common on a race motor?

You need about 170 degrees oil temp for 20-50wt. to have full flow @ bearings.If you don't have oil temp gauge that may take longer than you think to get oil to 170.
Usaully only thing we use 20-50 in is ran long periods,oval track,street and not worried about a little power loss. I still have alot of customers use 20-50 mostly blown or nitrous,they start cold and put in the water but they run .0035-.0045 bearing clearance,some of nitrous guys tried thinner oil and switched back.

FB,
If you are showing full oil pressure on the gauge, then you are getting oil to the crankshaft, so I would say the answer to your question is no. However ..... if you use an inexpensive filter and the insides come apart due to the high pressure and the blocked bypass, you will have a problem. But if this happens, you should also see a loss of oil pressure. I had one customer ruin an engine that way years ago when he switched to a cheapo filter. We found a clump of filter paper blocking the main passage into the engine :( |
