  • Ceramic Coating an Engine Block?

    Do you think it is feasible to ceramic coat an engine block without hurting the block? I'm wondering if the coating will hold in enough heat to cause the block to crack? Reason I'm even contemplating this is because I'm in the process of show polishing a cast iron 400 Chevy block. I'm looking into investing in some Mirra Chrome paint from Alsa and spraying the block once it's done being polished, but my concern is that the heat from the block will ruin the paint. So I'm looking for a way of keeping the chrome finish from getting harmed. Any ideas about this?

    Why noy just use the Super Chrome Powder, then clear coat. I've used many colors on blocks and never had a problem.

    Just 1 of many..

        I am concidering Ceramic coating a Block for the simple reason of keeping the heat inside and not heating up the engine bay. When you have a love of Mid-engined cars you do what you can to make it cooler under the rear deck lid.

          Becarefull keeping that Heat in as it will run the engine warmer!!! Causing a over heating problem..

            my only problem is where the exhaust passes over the block where the turbo is is going to need a sheild but i don't care it is a drag car it don't need to look that good under the hood just the rear end is what they are seeing

              Thanks for the all the replies guys, that helped me out alot. (I've got more supplies on order now, hoping to have this thing done within the next 10-12 days.) I'll be sure to post some pics when it's all finished. I'm stoked about this project.

                just pulled this power house out of the oven. just posted a geo block pictuer in the ultra 525 looks hot. should add at least another 20% to the top end. maybe i'll ad atouch of red and skip the nitros. I have a 383 in the garage that is completly ceramic coated goes in the boat. way over rated for marine just powder it. nothing on boat motor get hot with water cooled manifolds. just put the powder on it.

                  I wouldnt coat a engineblock with any thermal barrier coating, this keeps the heat in the engine and give it no chance to cool off by surrounding air. Caswell sells Techline, and Techline has a coating called TLTD, this coating is a thermal dispersant coating, thus helping the metal to shed off the temp. We use it on block, heads, intercolers, radiators and brakeparts etc. that needs to be cooled off as much as possible. TLTD is matte black, and looks real nice on parts, and more important, it does the job right.

                    Re: "Ceramic Coating an Engine Block?"

                    I don't know enough about ceramic coatings. But I do want to ask. Looking at the pictures of the engines you all have Powder Coated. Are you using "High temp" Powders? I ask, as I thought the "high temps" were only available in black & silver? But I see you all are using other colors? If you are not using high temp powder, is the regular powder holding up on the engines for a long time? Maybe the engine does not get hot enough to worry about the powder failing?
                    Thanks

                      The older engines run from 165 to 195 degrees. Most of the newer engines are designed to run 210 degrees. for a better burn. I have used acrylic enamels and polyurethanes on many motors with no problems. PC is better yet. Only on exhaust manifolds or headers do you need the high temp. coatings. As for the ceramic coating, I have only seen headers with this coating. Any coating that hinders heat dissipation too much is going to cause problems. Have you ever leaned on a car after it has sat in the sun all day?

                        Thanks Sswee:
                        I know the engine running temp is roughly 195F. But I thought the heat transfer temp (external) was much higher? Have you had ggod long term results using regular PC? Any idea what a motorcycle engine runs at?
                        Thanks Again

                          Can't say off the top of my head what temp. MC motors run. I would have to check but it can't be that much different even considering it being air cooled. Too much temp causes oil break down and detontion just to list a few. I have a 78 KZ1000 Police and a 82 Harley XLS. I can tell you the majority of colors on Harley motors is PC. The PC I have, I had done and it holds up better than any paint. I am just trying to get set up for PC now. Catalyzed polyurathane used to run a tight race with PC but since paint manufacturers pulled the lead out it don't seem as durable to me anymore.
