Plymouthy Adams Posted October 21, 2017 Report Posted October 21, 2017 page 150 of my 1946-1954 Plymouth manual clearly states the valve lash preliminary settings when cold Quote

Adam H P15 D30 Posted October 21, 2017 Report Posted October 21, 2017 Manual only lists .008 I and .010 E hot. I set mine at .010 Intake and .012 Exhaust cold and never looked at them again. Adam Quote
keithb7 Posted October 21, 2017 Report Posted October 21, 2017 (edited) Is there an aversion to setting your valves while the engine is hot and running? It seems to work very well. Edited October 21, 2017 by keithb7 Quote

I also talked to George Ashe son this morning and received basically the same info. He recommended .010 intake and .012 exhaust cold setting. Maybe going a little on the loose side, less chance of burning a valve. Quote

I am not a seasoned pro. However I I did set my valves cold, then later checked and re-set them hot, with the engine running. The exhaust manifold is hot. An average pair of gloves takes care of that easily. It's not messy. Pretty well most of the same steps are taken to set the valves cold or hot. The front wheel comes off. The inner fender window removed. The valve covers removed. Then the feeler gages and wrenches are needed. When cold, the engine must be turned over so that you are setting the valve clearance with the tappet 180 degrees from the top of the cam ramp. I believe TDC gets you there. Once set, the 6 cylinder engine is turned again another 120 degrees to set the next set of valves. In the proper firing order. You carry on, for each cylinder. With the engine hot and running, for example you put your .010 feeler gage in the exhaust valve/tappet gap and measure. If it won't go in the gap, clearance is too tight. If it goes in easily and ticking stops, then its too loose. I found that a proper valve setting, offered a slight tug on the feeler gage. It naturally wanted to slowly, and softly pull the feeler gage into the clearance gap while the engine was running. There is no mess. Oil is not splashing around and getting on everything. The feeling that l developed, of the running engine, the engine pulling the feeler gage in, was solid confirmation that I felt I had it set right. The fine threads on the tappets make for nice easy adjustments. After a few trial and error lessons you get a good feeling how much to turn the threads to make up a 1 or 2 thou adjustment. My engine is running excellent and I feel like I got the valve clearances right. Seems to me that setting the valves cold is a great start. Then put the valve covers back on and the front tire. Go for a drive and come back home hot. Quickly jack up car, pull wheel and valve covers. Access the valves and test the clearances with the car running. Its a nice confirmation. As you know, incorrectly set valves often leads to a mess of related problems. Yes its hot. Messy? I did not have a mess. I found it was way messier pulling the oil filter, sucking the oil out and removing the sludge, than setting hot valves. Good luck whatever you decide to do. I just thought it may be helpful to share my experience. Initially I was intimidated at the thought of sticking my hands in a hot running engine. Near hot exhaust and moving parts with tons of force. In the end I thoroughly enjoyed the new experience. Edited October 21, 2017 by keithb7 1 1 Quote
Adam H P15 D30 Posted October 22, 2017 Report Posted October 22, 2017 Unfortunately I have headers and you have to adjust them cold. Space is really tight. Adam Quote
bob westphal Posted October 22, 2017 Report Posted October 22, 2017 I hope you have the thin valve wrenches. It's wise to use tight fitting leather gloves. Quote
Adam H P15 D30 Posted October 22, 2017 Report Posted October 22, 2017 (edited) Agreed. Tappet wrenches are a must Edited October 22, 2017 by Adam H P15 D30 Quote
