Hey guys my 4ac is blowing a bit and using a mother load of oil (4-5 litres a month). I'm pretty sure the rings may be the cause. Is it possible to easily change the rings by leaving it in the car and remover head and sump or is it going to be a engine out job? Any help would be great

Depends how worn the bore is..

 

Its a schlep to strip it in place then measure the bore and find it needs a rebore anyway, so I'd pull it out and do it on the bench. You won't know anything until it is all measured.

 

Get quotes for complete overhaul, rebore, rings & pistons, crank cut, bearings, head job, then line that up against a second-hand motor that is just a drop-in. i'd guess you could fit 4 second-hand motors for the price of a rebuild, so its a gamble as to how good the wrecker's motors are.

 

Care for a 4AGE? Does it drop in easily?

Would it be easier to get a second hand one from a wrecker and rebuild that? Its my daily so needs to be off the road for as small amount of time possible

Easiest would be to get one from a wrecker and just drop it in, then see if you need to rebuild yours or just run the new one.

 

Maybe someone on here will have one they used before they swapped it for something faster, so they know what it was like.

 

Otherwise, it will be difficult to tell how good another one is. Check the condition of the car if its still in one, check the oil colour, pop a plug and see how much carbon is on it. Maybe you could buy a running car with one for less than $500, ratshit body, no rego but you can still drive it to see what the motor is like.

ive got a good 4ac if u want another 1 pm me
