The Stovebolt Site Forums The Shop Area Engine Shop 1929 Rough Running/ Sounding... Any Thoughts ??

Fired up the 1929 for a sound check, Posted it up to Youtube as well. Does not sound right to me, I know that i need to replace the oil pan gasket, as it is leaking.

Video is here: 1929 Chevrolet Engine Running

Anyone have any thoughts on what to check or look for based on how it is running ?? been scanning the manuals i have and going from there. Figure i should start off with the simple solutions and rule them out as i move down the complexity chain.

Thoughts and Opinions are Appreciated...

Would of been nice to hear it run at a different rpm... Also,it would be good to have a long handled screwdriver held against the camera body (instead of your ear) and move it around to different parts of the block to isolate where the noise is most pronounced... Otherwise my guess is oil pump return line...

main noise I'd be looking for is the regular 'clack' every second or 2, rest of it is probably valve train ... skip the screwdriver on the camera, use it on your ear, or better, use a stethoscope and narrow down the area that particular noise is coming from

Well yeah... use it on your ear first, but if you want US to hear it... use it on the camera and post that.
Bill has his horses in front of the cart... where as I was just skipping them all together.

Is it louder on the other side?
It almost sounds like a push rod is hitting the side cover or rocker oil supply tube.

Sounds like valve train out of adjustment, at the higher speeds you can here the push rod bouncing off the rocker arm. At slow speed its a pretty steady miss, a quick five count, almost.

OK, so got time a few weeks ago to remove the oil pan...

What a pain, not that it was hard to access, but the previous owner decided to remove the Standard Gasket and use the great make your own gasket in a tube method :/ What truely a pin to remove the pan that was adhered to the bottom of the engine. Had to drop the left & right underpans to remove all the goop tha thad oozed out, then use a razor & putty knife to gently separate the pan from the block. took my time and used some colorful language of how fun this was. but got the pan off, with out distorting or bending up the rails

also did a quick look up inside the block to check on things noted above. Here is what I found of concern:

1- With the Oil Pump: No screen (Part No 835779), just the Oil Suction Pipe, Guess Also need the Spring (Part No 346770)
2- 2 of the 4 Connecting Rods seemed pretty loose on the crankshaft, they easily and freely slid from left to right with out any effort. The other four were pretty snug on the Crankshaft.

Good thing was everything was coated and covered in oil, as well as all the troughs were filled with oil when I dropped the pan.

Here is what I have: scroll down about 2/3 of the page1929 Oil Pan Removal

OK, so was a good weekend to get some work done on the 1929 !!

I was able to check and set the clearances on the Rod bearings, and check the main bearings as well. Found out that all of the connecting rod bearings had too many shims, 2 of which i could move freely and easily with out ANY effort by hand as per above. Babbitt looked great on all the rods.

Also check the check ball and it is free and resting against the pin, and can be easily moved.

Cleaned up the pan, looks like it will need a paint job :/ so need to clean it up and paint it. But got time

Can paint while I am still hunting for the 1929 Oil Pump Suction Pipe Screen & Spring

Need to get this & paint the pan so I can install the Oil Pan Gasket and close up the bottom half of the engine and move to the top half.

I hear no noise at all now...lol
neat vehicle, you do good work

LMAO...

yeah funny Hopefully it will be a lot better once I get it all together, going to have a local shop here dip the oil pan, valve cover, and push rod cover to clean them up and do a few weld repairs on them for me. then I will prime and paint them then reinstall !!

and finish up my tune-up fix up...
