Smoking tractor

Darwindo · Dec 17, 2011

I know it needs rings and some valve work which I will do later, but does anyone know of an oil or gasoline additive that will reduce the amount of smoke belching out of a 63 year old tractor, until I can get around to the real work that needs to be done?

Things that might help are these. Park it for a few days and pour in about a 1/3 of a cup of ATF into each cylinder. Doing that frees up sticking rings and also helps clean out carbon that may have built up bot of which will cause one to smoke. Also going to a straight weight oil like a 30W in winter and a 40W or even 50W in the summer helps

Make sure the air intake isn't plugged somewhere--collapsed hose--dirt in the air cleaner.

Out of my H, MD, and SMTA I haven't seen one that is good looking inside the air cleaner. I soaked my last one in Dawn for a day and then hit it with the hot water pressure washer. The other two just soaked in the parts cleaner for a day and then blown out.

is that gas or diesel your talking about?"smoke belching out" sounds like a detroit diesel on startup.seen some pretty worn out gas engines but havnt seen the oil belching out, if its that bad then nothing will cure it.you sure all the pistons are in it? might have to put it on the patch or give it nicorettes.

It is gas, and I know the rings are bad, but before I pull the head I will give the nicoderm a try.......why didn't I think of that?

Of all the oil additives, Lucas is the best one for "loose" tolerance engines that smoke. As has been stated, a little ATF in the cylinders or Marvel Mystery oil will free up sticky rings. Sea Foam is also a decent product, but pricey.

If your rings are truly worn out and the valve guides worn, no additive will fix that. However, if the rings are just sticky, ATF or MMO will help. Lucas oil additive in about the only product on the market that I will spend money on, and it too won't solve a worn out engine, but it will help. Depending on what your climate is, you can also step up to straight SAE 40 as well, unles you use it during really cold periods.

I had an old Datsun pickup truck i ran around the farm. was plum wore out, and I ran sAE 50 in it to keep the oil consumption and smoke down......

A mechanic for the road crew that did our highway in the '70's said when a dozer/ scraper/ heavy equipment engine started having oil go by the rings, they would switch to #10 engine oil. The theory being that the oil would get off of the cylinder walls quicker than heavy oil would.
