[Mk2] [Turbo] 3sgte oil pump questions

[h20490]

After sorting out the headgasket (cometic/ARP headstuds/top end) and rebuilding the top end and replacing all the belts after 1500 miles ive just found a leak and its coming from the oil pump

bought a proper lemon.

can a rev3 oil pump fit a rev2 without any/much modification?

and where's the best place to get an oem one?

wish I hadnt diagnosed the leak today I can see it just dripping out when I start the car. so looks like im without a car again

Awesome cheers for that link

How much do you think a garage would charge to get this fitted as I really CBA taking the belts off to do this?

Found out some information on this thread which has cleared up most of my questions.

Where is the oil leaking from? I have never known one to leak before.

More likely to be the crank oil seal, which do have a reputation for leaking after lots of miles/ years

[h20490]

I would be replacing the oil pump , crank oil seal and waterpump if Im doing this job.

I dont think it is the crank oil seal as the area has been cleaned and checked a few times and deffo seems like its from the oil pump

But where on the oil pump is it leaking from? Are all the bolts tight?

[gavinda]

have you checked its not dripping down back of engine from camcover corner (problem on rev2 head) above alternator or cam seals if youve had cams out. this is more likely than the pump leaking.

Its coming from the bottom part of the housing. all the bolts are tight. only leaks when I start the car hope that helps.

another look and as Bob says its ACTUALLY coming from the crank end seal

I think im just going to take the engine out and rebuild it or get another and get all the servicable parts done to it and fitted in.

My mr2 ownership hasnt been too great so far and im only 1.5k miles in

You don't need to strip the engine to change the seal mate, it's a hassle but you can do it with the engine in situ

[h20490]

I know Ash

But at least I owned up to it.

I know it can be done it situ but as its already had all the belts recently replaced and my turbo is also looking like it needs to be replaced, the best option is to take it out.

With it out this means I can do the oil pump, crank seal , waterpump , turbo (c20b/GT28) and also do the hoses from hell whilst the engine is out as well as any other bits that might need doing.

[bobhatton]

I have the repair kits for the CT26 and CT20B turbos if that needs to be repaired when the engine is out.
Please buy all the parts from Toyota, not from Ebay, you do not want to be doing the job again soon.

Dont worry Bob Ive rebuilt a Honda Crx turbo (b1a1 with a T28 Garret) before and used only Honda Parts and gaskets bar the ARP headbolts and flywheel bolts etc.

Like I say the head has been rebuilt with ARP parts and a Cometic triple layer headgasket.

Im so annyoed that the car has had a headgasket rebuild before me and they simply put the fabric one back on!? madness

I will probably grab one of the seal kits although I will deffo be replacing the turbo just weighing up options at the moment.

Thanks again guys
