I am rebuilding an Oliver 1655 diesel. The block was cleaned and blasted at the machine shop. I am painting the outside with epoxy primer and acrylic enamel, but a post on the paint board got me thinking about the inside of the block. It was suggested I could paint the inside cast surfaces with glyptal. Any thoughts on painting the inside vs. leaving it bare cast? It is a work tractor, but after spending this much money I want to make sure it is done right.

Josh, Solvents and oil don't bother the glyptal, but water and anti freeze will peel it off and put it in the sump screen . Had a customer come in with a 396 chevy with a leaking sleeve ,the block had been painted inside with glyptal . The anti freeze and water peeled it off , what a mess.

Go get a can of cast blast or last blast , it is the gray paint that the rebuilders use. The oil and water don't bother it , been using it in rebuilding engines for 25 years .

Eastwood,one company that sells it has a forum[Eastwood forums] maybe you could ask over there.They let guys complain about products without deleting the posts.I dont think it chips off it might sort of slowly wear away after a long while.Ive seen it worn down in old Harley motors.Just read a thing on the Hastings site about blocks being magnetized and holding steel shot in places even after cleaning.When demagnetized more steel shot falls out.I see it costs 54.99 a quart or spray, so it aint cheap.Might try an electrical supply house for a better price.It sure seems expensive.

Glyptal is not an ordinary paint. Its one that does stick well, and isn't affected by solvents. You have to wear the skin out from under it if you get on you and any patches on your jeans will still look good when the jeans are in shreds.

It sticks and lasts even better when baked.

You'd have to clean real well, debur, polish and use the Glyptal enamel for that. BTDT for race engines and has to be really clean to stay stuck. Not worth it for your application and don't use the cheap rattle can primer or you'll find it in the oil pump and on the screen later after pressure drops. If you decide to do it Glyptal is available from major paint suppliers like Sherwin Williams or thru Eastwoods restoration supplies. Glyptal is actually and red colored electrical insulating enamel.

I wonder, even after cleaning, if the (porous) cast iron would be oil-free enough fot the paint to hold as well as it did when the block was new-cast?

Would the naterial painted on the used block be more prone to peel or flake off over time?

It is one of then things that yes you can paint the inside with that paint and no it is not nessary . They use to paint the insides of some engines and this was done to SEAL any imperfections in the block that may let oil leak out . IT was done alot when building race engines so that oil would return to the pan faster . But for what your doing , No i myself would not do it have not done it in over thirty years it is just about like setting there with a die grinder and polishing the inside of a block to make glassy smoothe and to loose a couple pounds of weight . Put the thing together and don't worry about small change just do the best ya can on checking everything in the clearance dept. as to bearing clearance and piston fit that is alot more important .

Well i know i have been building engine for a lot of years from mild to wild and built some that you have probably never seen and only painted three and it was more trouble then it was worthe Now maybe if ya dipped it first then machined it it would be alright. Even spent time grinding and polishing the inerds to a mirror finish here again did not see any advantage . my time is maken them fit best spent .

What kind of engines have you built? After reading a little about glyptal I think if i was building a race engine I would do it, but this is a tractor. Hopefully it will be together for 20 years, and maybe a lot longer. It made it 34 years the first time, and probably will see a lot less use in the next 34 years. I am concerned that after 30+ years the glyptal could be broken down, and start to clog things up?

I am not familiar with the Glyptal product mentioned in the reply below, but it might be what you need. You definately do not want to use ordinary paint on the inside of an engine. It will quickly peel and flake off and could easily plug the intake of the oil pump.

Hi Josh.

If it was me, I would leave the inside of the block alone, and not paint it. Over time the oil will start to break down the paint and chips will start flowing in the oil, and you now risk having oil passages blocked. For the most part, the oil protects the inside of the block and the paint protects the outside of the block.

This is just my opinion, for what it's worth. If I'm wrong, someone feel free to comment.

GLYPTAL WILL GREATLY INCREASE THE OIL RUN-BACK RATE TO THE SUMP, AID IN COOLING BUT MOST IMPORTANTLY, SEAL ANY DEBRIS LET BEHIND FROM THE CLEANING PROCESS. (sorry, caps were locked !!)
