Engine out of the MR2, started to strip it down

[mark239]

Had a slight overboosting 'issue' the result of which was an erratic idle and smoke from the breather hose. All things pointed toward ring gone on piston no 1.

Well, took the engine out of the MR2 yesterday and spent most of this evening stripping it down.

Here are a few pics of my ordeal. Forgive the quality, theyre all off the phone.

First couple of hoses off


All pipework off from the top, ready for dismantling crossmember & suspension underneath


A shot of the inlet with the injectors exposed, and some of my labelling


Another shot of my masking tape labelling system


Got her up on the lift then to remove this beasty (Yes I know the shafts are off in this pic, it was the only one I had of the crossmember still in the car)


Tie bars then came off meaning I could swing the hubs out


And then pull the driveshafts out


Disconnect the droplinks, and get the bugger out


We then raised the car away from the engine on the lift, and I was extremely glad to be left with this when the lift went up




The pile of parts mounting in the corner


Have a look at this for a hosing nightmare - This is going to be a nasty one to replum!!




This is the last time this turbo will be on the engine


Head off


And the block


After all that I'm well knackered, and there is at least as much work to go! I have all the bolts out of the gearbox and will split it from the block tomorrow. Have a 6 plate clutch to go in there to take the new horspepower and torque!

Update - the damage

Well, got the sump off:



Extracted Number one piston and saw the damage after I wiped the oil off it.




I tapped the back of the piston and the bits broke off!!



Thank god I didnt drive it hard or far with the piston in that shape or I would have been looking for a new block as well !!
