After I got my engine rebuilt, it smoked a lot at first too. After a couple of warm ups it stopped smoking completely. How long have you had the replacement motor and how many miles did you put on it?

Have you spoken to your engine builder about this? He should be able to point you in the right direction.

And i've seen he actually has participate several times here in this forum, he makes rebuilds..

I have like 400 miles already, i put the plugs recently, but as you can see it looks like the second cylinder is wrong or something because old plugs were in a bad shape but the ones on the second cylinder...

'not having to add coolant' is a terrible way of testing for a coolant seal failure. it's like checking the fuel gauge to see what your AFRs are. you can have a failure that isn't leaking enough coolant to be noticed, and you can lose coolant for other reasons.

get the oil lab tested for coolant, the coolant tested for combustion gases, check for coolant in the housings on a cold engine, and/or pressure test the coolant system

Fixed. Your engine has precisely zero cylinders.

if you are not losing coolant then you are fine. all cars steam bit when its cold outside.
see how mine steam when its cold out?

What is builders response about the engine?

If you pressure test the system and it hold pressure, you don't have coolant seal failure. Ideally you could get the oil lab tested but why go through the hassle? A failed coolant seal will push coolant into the combustion chamber during a pressure test. How many miles on those plugs?

But a failed pressure test does not mean a coolant seal failure. A failed oil test, finding coolant in the oil, or combustion gasses in the coolant will all conclusively prove a coolant seal failure. Sure, a failed coolant pressure test will certainly show that there IS a problem, but not where.

richcoto

Yes i know it has no cylinders, but let's say the second chamber then, plugs are like 1 year, maybe more, thing is, recently changed oil, it looks fine, it steam a little bit in the morning and a little bit more when i stop the car for awhile, so, i need to see how it goes, thing is when i high rev the car it gives me p0300, pressure test went well, i'm not loosing coolant, and last time i loose a lot of oil, but after the temperature was fixed, oil is not lacking too much, thing is i have to test...

Builder (Tim Benneth) stoped responding me some time ago

jasonrxeight

maybe the its a sign the builder stopped responding you cuz you seem to just coming up with random conclusion.
steam on a cold car is totally normal, dont worry about it.
if you are not losing coolant then you are not losing coolant. how hard is that to understand? stop beating a dead horse.
anyways, p0300 means random misfire. put new plugs, wires, and coils in then report back.

I just realized that this is a continuation of a prior thread.... getting merged.


richcoto, I recommend that you take a video of what you are talking about, and post it up.

I should have noted that a failed pressure test does not mean coolant seal failure if there are other leaks present in the system. If the system does not hold pressure, and there are no external coolant leaks, they have to be getting past the coolant seals.

richcoto

Plugs are new, coils (6 months) Black halo, coil wires NGK (6 months) not loosing any coolant but loosing oil, so what it's being burned it's oil and not the regular lost of oil that we all know it's regular... i have to put oil on it every 300 miles..

it steams a lot on the morning as you can see in the video, and everytime i shut it off...

and it's not cold outside at all..

there is the link of the video, i didn't find how to embed it to the post, but the youtube link is right there...

Hmm. Yeah, definitely not normal. Figured it would be good to rule out normal condensation.

It does seem to have a bit of a bluish tint to it.

richcoto

yes what i'm sure is not a coolant issue, it's an oil issue, and i'm starting to accept it's an intern oil seal what is damaged... and it's the back chamber as it gives me p301 sometimes...

If the engine is open to fix this, what shold i buy ?
