Amazon: Bent Push Rod

[ColoradoAmazon]

I'll try washing it off. That makes me feel a little better. Thanks!

I put the new push rod in and adjusted the valves. They really weren't that out of spec in my opinion. I would say the worst one was maybe .022"/.024". The springs don't look like they are binding so I'm a little confused why this happened. The engine seems to be running fine and I have compression in cylinder #1 again.

I'm a little worried about my oil pressure. I'm getting 20-30psi (I haven't revved the engine past 2.5k rpm or left the garage yet) on a gauge I installed. I'm using Royal Purple Engine Break In Oil that is 10W30. So maybe that could be it.

Does that valve train look dry (this was after running engine for 1-2minutes)?

I am thinking that you might have a flow issue. On my B20E, if I remove the oil filler cap at idle I will get sprayed with oil being flung off the #1 rockers.

When I started up my B20E after its rebuild, I removed the oil pressure switch and manually rotated the engine over multiple times until I got oil at the oil pressure switch port, re installed the switch and then with the spark plugs out used the starting motor to turn the motor over until I got oil coming out of the rocker stand. If the engine had been running for 2 minutes I expect that you should have oil flow at the rocker stand.

There is a procedure where you can remove the distributor and with an appropriate adapter use an electric drill to rotate the oil pump drive to cause oil to flow through the engine prior to a first start. The down side is that sometimes getting the distributor mated up with the oil pump again with everything in the correct position for timing can be an exercise in frustration.

I would be inclined to pull the plugs and crank the engine to confirm that you are getting flow out of the rocker stand. As I recall, oil flow comes up through the block between cylinders 2 and 3 and then takes a little bend through the head and enters the base of the third rocker stand. All 4 rocker stands have the same part number so it does not appear that mixing the stands during re assembly could cause a problem. If you ae not getting good flow then I would be inclined to remove the rocker stand and then crank the engine to see if you are getting good flow at the #3 rocker stand base. If not, then I think you have some disassembly to check for a flow obstructions. If you are getting good flow, then you may have to partially disassemble the rocker stand to check for obstructions.

At 850 RPM idle, my engine with a new oil pump has a pressure of about 15- 20 psi running 5W50 full synthetic. Oil pressure very much depends on temperature. On a warm / hot day, 20 psi at idle with 10W30 is probably in the ball park.

CA;

I agree with 142Guy...I would also expect oil at the rockerworks and under the Valvecover after 2 min of runtime...and since you've experienced a Bent Push Rod, this could very likely have something to do with it (likely be the cause, so you may have just found the root cause...!).

If it was me, I'd remove the entire Rockershaft assembly, disable Ign, pull Sparkplugs and crank away...there better be oil getting pumped up to the Rockershaft assembly!

Good Hunting!
