rings

[scruff123]

hi all, just wanting to know the symtoms of a broken ring, i think i mite have one but hoping not.
i have;
-allot of blowby
-crankcase pressure, rear main seal is seaping oil and front crank seal
-trouble firing up when hot
-using a fair bit of oil, about 3 ltrs between changes(5000ks)
-very slight ticking noise


the wierd thing is is it still runs sweet with plenty of power, and doesnt blow any smoke.

any ideas on what could be rong?
and also do u have to have the engine out to replace the rings?

cheers

Dont sound good but its more likely worn rings not broken. Also risk of damaged bores.
Did it go like this suddenly of has it just slowly got worse.
I believe rings are an engine out job especially as its wise to do bearings at the same time.
A catch can might solve the oil burning
What mileage?
worn rings come from huge mileage (we have evidence of those motors with over 400000km) or lots of short trips or poor oil change practices somewhere in its life.
Worn bors can be big mileage but also short trips cause acid to form in the combustion chamber which eats the chrome This was more a problem with the old high sulphur diesel.

its only done about 60,000ks on full engine rebuild thats why i was thinking it mite be a broken ring not worn rings? its had the slite ticking noise for ages but all other problems have slowly got worse. i have a catch can but it still uses allot of oil.
i dont really want to take the engine out so is it possible to do them with it in?
will a compresion test confirm if its rings or not?
i do about 2 30km trips a day and afew long trips most weekends, have always changed oil every 5000ks max and run good qaulity oil.

Is there still a warrantee on that engine. Even if there isnt I would still talk to the reconditioner.
was it a full recon with new liners etc, Was it done with genuine chrome liners or aftermarket iron ones. If you dont know you cant buy rings till you get it apart as one side has to be iron the other chrome ie chrome rings on iron bores or the other way round.
Compression test might tell you whats going on

[scruff123]

no warenty, it was done just before i brought it by the mechanic who sold it 2 me, can ask him if he used genuine ore aftermarket ones. going to get a compression test done this week, hopefully find out whats going on

[geeves]

He probably just put rings in it

I know this might sound stupid but your not over filling it with oil are you?? that would also cause all the simptoms you discribed

na mate shes never filled over half

[scruff123]

im going with a full rebuild, i can get a full rebuild kit for around $800 and got qouted around 1500 for getting the work done, is this a good price????

[pig75]

A rebuild kit here in oz over double $800 for a 3.1 sounds like a great price

[geeves]

It will be an aftermarket kit with iron sleeves and chrome rings. Nothing wrong with this as long as next time you do rings you remember as iron rings in an iron bore or chrome rings in a chrome bore dont last long

[geeves]

don't commit to a full kit till you have the head off It might not be needed

[scruff123]

so i decided to do the work myself, got the head off and every liner is slightly scored, just about to take engine out and need to no if i have to drop the trans down?? got all the bolts mounting bellhousing to engine off but it doesnt want to budge?

also found out that only one liner and piston was replaced!
before i had it it ended up 2 stoking and put a hole in one piston.

gonna do all the coolant hoses wile the engines out, can anyone tel me were you can get all the right hoses?

anything else i should replace wile havine the motor out?

cheers

get the complicated ones from Holden the easy ones can be made from straight pipe.
You might save a little matching them at ripco or notsocheap but its not worth the effort

cool thanks for that, what about my transmision will i have to drop it out to get the engine out?

[scruff123]

can anyone tell me how to seperate the enghine from the trans?? have all the bolts out and it just wont budge.
anyone got any tricks??? getting very frustrating!!!

[geeves]

Put a couple of the bell housing bolts back in. Reach inside the bell houseing and undo the 6 torque converter bolts turning the cranck to get at them. Then remove those bellhousing bolts

[scruff123]

were do i get inside the bell housing? is it the flat plate at the very bottom? cheers

[Blondini]

take that plate off to get to the bolts

[scruff123]

awsome thanks heaps guys
