Hmmm, I have a 1990 honda civic that smokes like a freight train. I mean, James Bond's car ain't got nothing on my smokescreen. I will try a couple cans and post back on results.

Just a side note, I am an auto technician, and have little to no faith in "mechanic in a can products. I am highly skeptical that this product is anything but a wallet drain, but I am willing to try it on the worst car I own, and see if it has any effect good or ill.

If it's really smoking that badly then forget it. FWIW, I went to school for auto mechanics way back in the dark ages and was skeptical too but a late friend who was a GM mechanic for 25 plus years talked me into trying it on a bet. He won.

Hello from central Florida. I'm not a hot rod guy but I do like to restore old boats. I just purchased a 1947 Jafco with a Chrysler marine straight six. It smokes a little and has lower compression in the NO 5 cylinder. It also has a little crankcase blow by. I am going to try Restore and see what happens. I have compression numbers for the engine and oil pressure readings. I'm not sure why no one else has recorded compression readings beforehand but we shall see what I get afterward. I know this post is old but it did convince me to try it. I will keep you posted. Thanks, RWC

Hi - this is an interesting thread. A lot of controversy over "engine restore". My 4 cylinder engine is smoking badly with some blowby. Cylinder 3 has been weak for years and would foul the plug but there was mild smoking under load. I gradually moved to a 25-60W and onto a higher heat range for that cylinder and cylinder 4 followed fouling. I even put oil non foulers on plugs 3 and 4 to reduce the oil fouling. The maintenance on the engine has been lousy and going heavier oil/motor honey is not improving the smoking. I added a MLB8 concentrate that looks like a thick creamy copper sludge that is mixed with some motor oil and added to the crankcase. I dont know what got into me but I took it for an "italian tune up" and drove it hard on the freeway for about an hour. It was still blowing smoke and running rough when i got back home.

I checked plug 3 and it had detonated which shocked me because i didnt expect it to get that hot.
What was a low compression oily cylinder was now reading on par with 1 and 2 and a fresh plug is now sooty. Cylinder four didnt detonate but i had a colder plug in it, on an oil fouler and the compression was found to be quite low. The van was still smoking badly and so i changed out the oil and flushed it again and changed the filter. I changed to a hotter plug for cylinder 4 and the motor runs better but still smoked.

I added a can of "engine restore" and let it idle at about 1500rpm for an hour. No more hard driving this time - i dont want to risk damaging the motor any further. Its just weird how plug 3 which was always a hard plug to fire got hot enough to cause detonation and now has improved compression.
Cylinder 4 has poor compression. It didnt get as hot as cylinder 3. It has become more of an experiment to see what these additives might be able to do.

I ran out of the other concentrate and had a can of "Engine restore" to try. This product is suspended in its own oil and just added it to the crankcase with fresh oil and filter. There doesnt seem to be much of the coppery stuff in suspension and the carrier is a lighter oil than my engine oil.

Anyway, I upped the heat range on plug 4 so it runs hotter to see if it helps with the "plating" idea. I let the engine run just above idle for an hour or so and checked on it periodically. It seems to have more pep but its still smokey. I am waiting on more MBL8 concentrate. If these products can cut down the smoking and improve engine efficiency then they are worth exploring. The valve guides are probably fairly worn and the engine may be too far gone to stop the smoking but it makes for one great opportunity to give it a try!
After all, its a well worn 30 year engine.

You guys are lucky you get "engine restore" so cheap. We pay $30ish a can over here and thats if you can FIND it! The reason i am trying this is because rebuilds have been quoted from $2000 to $2500 and parts are getting hard to find.

This restore thread is old and so far it`s living up to it`s name as this old thread keeps getting restored. Way I see it is when your engine needs a kick start, pour in a couple cans of Blatz beer and let it rip.

Yes i know its an old thread but an interesting one nonetheless. I know its a hotrodders forum and way outta my league but this forum is one of the most civilised and helpful ones that discuss it.

I came across this site out of curiosity about engine restore, bold claims with pretty little graphs on their website but being a skeptic towards any of this stuff and after 9 pages realizing not one person has actually done a compression test before and after so I figured why the hell not do it on my civic since plugs are simple to pull. So here are the before numbers, after 500 to 1000 miles I will post some after results.

95 honda civic lx with 216,000 miles

compression numbers are 158, 145, 150, 168

Factory specs are 185 new and 135 min i believe

I also plan to change the oil and see if the after numbers drop once the stuff is not actually in the crank case. either way the can has a guarantee so if it doesn't work I get my $6 back

Who the heck wants to do a compression test on a crappy old beater? ESPECIALLY a GM FWD V-6 which is primarily what I used it in. If the first can works for you, you keep using it. If it doesn't you're out $6 and won't buy it again. It's worked for me many times but has finally met it's match on my current 305. Nothing is going to help this one except a new engine. Still using it successfully in the 3.1 Grand Am though.

I put the stuff in my brother-in-laws '69 Nova that had been sitting for a couple of years some time ago. Got it started, put it in, did nothing for the oil burning piece of junk, a total waste of time, fortunately dirt cheap.
