Much Ado About Nothing

Thought id stop by and banter a bit about what ive been up to lately…
I took the old Plymouth for a long overdue trip to the gas tank repair shop, where it was treated to what turned out to be a rebuild of my fuel tank, it had a lot of rust in it and some pinholes as well, so it got cleaned, baked, lined and now even the gauge works! ( It never had , as long as i owned it anyway) so, with that out of the way i had to turn my attention to the old Chev…
Had to get some new tires for it as the old bias tires were cracking on the sidewallls , so with that done i then turned my attention to the engine…
Its a 235 6 cylinder, and late last year i discovered that # 5 cylinder was not working, so the other day i did a compression test, found that 110 PSI was about the norm throught till i got to # 5, it had about 40 or so PSI, so i squirted some oil in the cylinder and it came right up, which is an indication of a sticky piston ring.
Ive seen various thoughts and ideas on fixes on that on various sites on the net, anyone here have any ideas on what easy fix may work?

I dont have any tried and true advice..
seems like Ive heard of folks running kerosene or diesel thru the crankcase for a time…
Hopefully there will be some replies from backyard mechanics..

Hi Bob - For your sticky piston rings you might try Lucas upper cylinder lubricant. The quart size treats about 100 gallons of gas or diesel fuel. It’s a product that removes carbon in the cylinder chamber and injectors. I have used it in all my engines and have seen an improvement in compression. It’s readly avaliable at most parts stores. I’m not sure but I think it was highly recommended by Auto Restorer Magazine.

yeah that lucas stuff rocks, i try to use it every other tank. u might try putting some marvel mystery oil in crankcase in addition, or maybe some engine flush (basically diesel fuel anyways). let us know the outcome! :slight_smile: --j

So far ive used Lucas upper cylinder treatment and sprayed some penetrating spray into the cylinder and driven it about 100 miles, seen some improvement but as the advice of a mechanic i asked, it will take awhile!
