Problems... No boost & radiator leek

[St3ve]

Hi.

I had my car fully inspected last thursday. The results of the test werent all that good.

The major problems were:

bottom tank of radiator leeking coolant

This is quite bad. leeks pretty constant, coolant level always quite low because of it. Should i replace the radiator with a 2.8l one? have the current one re-cored? change the thermostat to a more suitable heat range for aussie? suggestions please.

turbo not boosting

This is kinda sad for me car doesnt drive that good. quite slow. i can hear the turbo spooling, but it doesnt have any boost. the guys at the 4wd place suggested to get a compression/leekage test before going ahead and looking at fixing this kinda problem, coz head might be gone...

The car also goes thru a bit of oil. has a few leeks from motor at sump rear main and tappet cover. on cold starts lately, have noticed whiteish smoke. could this be a sign the turbo is screwed???

THanks for your help guys

If it's only the bottom tank leaking, a radiator shop should be able to replace the tank or solder it.Do it now.........right now, don't risk a catastrophic coolant loss.
As for the boost, firstly, I'd go and buy a boost gauge (they start at about $45) and see what boost you're actually making.
It's best you know the facts before you start speculating possible causes.

White smoke is generally coolant.

i got the radiator repaired yesterday. also did a flush and new toyota red coolant. got a new thermostat from toyota also for AU$22.95! which was great i thought.

although, i havnt noticed a difference in temperature. needle is still at half way, and to touch the top of the radiator, and the hoses/pipes etc, its very hot. thats normal then i take it??

but no leeks anymore which is good

still not sure about the boost... i will look into a boost guage but. thanks

Nice that the top of your radiator is hot...but more important that it is a similar temp to the bottom.
It's common for the system to be airlocked after a refill , you probably wouldn't notice on the temp gauge.

I will keep an eye on that. thankyou

Just make sure front & rear heaters were fully open when you flushed and refilled and are now working, rad hot all over and the rest of the pipes. Check coolant level often for a few days to make sure there are no air locks that have moved.

Turbo boost pressure

My turbo stopped working a couple of months back and still havent found anyone to fix it yet. Had all pipework checked for leaks, they were Ok, wastegate is fine and turbo itself is OK. Got a mobile diagnostic guy to check it over and found a fault with the coolant sensor!!!!???? wont be using him again. Took it to Hills Toyota in Bishop Stortford but they couldn't guarantee that their diagnosis of a faulty pressure sensor was correct, in other words if i get them to do the work for around £450 (£208 for the sensor alone!) and it doesn't fix it, well then i guess its just tough, why do things have to be so difficult?

Why not put a post in Parts Wanted

thanks
