OK this is what is going on, my motor is burning oil and i mean too much (And I know ludes burn a lot of oil) my problem is the coating on the cylinder walls (frm) is coming off and i need to get it sleved.

So what i need know if anyone knows any good shopes in the New Brunswick , Canada area that can do it . and what kind of sleves and pistons should i use. and what can i expect to pay for a job like this. and how long of a process does it take.

 

how can the frm be coming off, do you mean the liners you have are worn or out of spec, frm isn't a coating as far as i know. have you had the head off and stuck a bore gauge down it

 

i honestly dont think its your liners

 

you have a coating on your pistons and you cylinder walls called (frm) this wares down over time comin problem with the h22.

 

well if its a coating and its coming off there's not much point in overboring i suppose, i know from experience in bmw's ( the whole nikisil liner thing) that coatings are ****. allthough a lot of guys on here say the liners are strong and are NOT a weak link, if your burning oil it could be oil control ring or just your rings getting glazed. how much mileage you got?

 

140000 km not Miles
and trust me i know what is wrong with this car i love the thing but were i live there is only one great mechianic and he does not have the machine to do the work. so my two opions are fix it or get a built motor. right now i think fixing is cheaper but that is what i am trying to find out with this post

 

dude, frm is incredibly strong stuff. Its not a coating, its the material that the cylinder walls are made from. I bet that your piston rings are worn.

 

fair enough, if you've done all your compression tests and your sure that bore wear is what it is, any engine builder will either be able to do it or recommend someone who can. Getting it done is the easy bit, its payin for it thats hard. buying a new engine is a pain in the ***, better to just build it up, atleast u will know its strong and not likely to fail. i'm just really suprised your liners have given up so soon

I gotta go with a big NO on that one. Don't act like you're educating people when you really don't know what you're talking about.....please. You yourself sound like an overconfident mechanic who thinks he's right about everything....

The sleeves are made of FRM (fiber reinforced metal), it's not a coating.

sorry I must have read wrong before but i have done the research and me and my tech are sure it is the cylinder wall and the coating on the pistons. and if there is anyone who does not believe me that the h22 is a weak motor ask a trubo guy he will tell you that you have to sleve. unlike the B18C

Any ways can anyone help me with my first question. I don't care what the motor is made of I just want answers

thanks

The reason turbo guys have to sleeve with the H series is due to the fact that the stock pistons have weak ring landings. To put beefy FORGED internals , you must use Iron sleeves. The FRM prevents the use of forged internals unless the pistons themselves are coated with some type of material, hence the JUN piston and Mahle Gold piston. The sleeves themselves aren't the weak part of the motor.

Reading is your friend.

If you are burning an insane amout of oil, hone the block and re-ring the pistons.

weak motor? are you freaking kidding me? The people that think the h22 is weak are the same dumbasses who blow them up cuz they didnt know what the hell they were doing. There is absolutely no coating on the pistons or on the cylinder walls. The cylinder walls are made of a specific kinda of metal which has fibers layed into the metal to increase the strength of the cylinder walls. Another point to FRM is that it is used to reduce wear and is used as a heat resistor.

The only time coating is involved is when you are dealing with the Mahle pistons or the JUN pistons (not sure about the JUN pistons coatings). In order to run the forge piston in the FRM cylinders you have to have a special coating on the piston skirts so they dont scrape the walls.



THAT has a coating on it.

 

ok i am not going to sit here and fight with you guys if i am wrong i am wrong and i am sorry for that but just please help me figure out witch way i should go.

thanks for all the infor so far

 

have to taken the motor apart to confirm that your rings are toast?

have you done a leakdown test to give the leakage %?

Have you done a compression test?

Yep, there's your first steps right there.

 

eh, someone just got slapped, lol
