Getting to the piston rings?!

Post by ABleach » 19/05/17 21:24

Hi mates,

I am finally in a position to give more time back to my 1992 mr2 3sge import

I am currently in the process of stripping it down as i either have a battered headgasket or (most likely) piston rings. Having never stripped an engine before i am trying my best to take it all in, i am currently at the camshafts and obviously need to get beneath them! Note that the engine is still in the car and i'd like to keep it that way.
So, how would YOU go about the next step?

Thank you for the advice and sorry for not knowing too much!

Cheers,
Alf

Hi Alf,

I have just rebuilt my 1994 NA and although I'm no expert, I would seriously consider dropping the engine/gearbox out unless you have a pit or a lift. I took mine out for the first time on the drive using a couple of jacks and axle-stands in about 4 hours so the job is not as bad as some make out (assuming you have a reasonable tool kit). You don't need an engine hoist (but I'd recommend using one) - you drop car down until the engine rests on a trolley of some sort and then carefully lift the rear of the car up high (1m or so) so the engine can be pulled out.

You can remove the head in the car: leave the cams in place and undo the head bolts in the order specified in the manual but if, as you say, you are intending to take pistons out, you really need to take the engine out to properly clean and inspect/refurbish the block. Leaving the block exposed outside will risk ingress of grit which will quickly be terminal...

Thank you for the reply mate,

I will consider that, now that i have my daily i am in no rush apart from the rush of wanting her back haha. I think removing the engine will be much more beneficial for the car and for me learning actually. This said i will remove the head within the car and see the damage, if there is nothing evident i will button it back up and drop the engine,

How do you think that sounds?

Cheers

I would drop the engine anyway if you are going to be doing more than just gasket and looking at bores.
Easier to do water pumps and belts etc when putting all back together.

Have you got the BGB downloaded? its always a help.

You can't just fit rings. The bores will need to be checked and measured and they will also need to be honed at a minimum. Engine out is the only way to do this correctly. Also cams can stay in the head to remove it.
