Hi gents,
I'm having real issues with a 2006 Avensis 2.2 D4D diesel I have for sale. Suspected head gasket but isn't really showing any of the classic symptoms of a blown head in my opinion.
Thought I'd post here as the technical forums on PH are like ghost towns!
Anybody familiar with these cars please get in touch.
Cheers,
Alex

Hi Craig,
I have recently sold the car to my customer and had to take the car back after Toyota did a F.o.C 'Visual safety report' and said they suspect the head gasket has gone. The problem is this is no easy fix and unlike throwing £500 at a Rover K-Series to put right, there is a strong chance this could mean a crack in the head for my Toyota which is terminal.
Upon me buying it the radiator was t*ssed; the temp was creeping up on a run just beyond half so I replaced that at huge expense (£300 for a rad!), this was after pressure testing the system, just to be sure.
I ran around in the car with no issues for a couple of days before I sold it. Customer takes the car 140 miles and then gets back in touch to tell me the temp has gone all the way to the top. I retrieve the car, first of al check the water, and was surprised to see that it took 2 litres. I drive the car home 140 and all is A-ok, temp needle did not move from just below the half way mark the whole journey. We pressure test it again up to 2.5 bar, and all is well, so between my mechanic and I we put this down to a possible airlock in the new rad.
Phoned my customer, informed him of our findings and he is happy to take the car back. I deliver the car and cover another 140 glitch-free miles on the motorway last night. I drop it off at his house and show the customer the position of the temp needle having just come off the motorway. We exchange cash, part exchange, and documents etc and off I go back to the north west. Then the phone call comes 20mins later. Temp is fluctuating and going as far as the red once again. I did not initially believe him, so turned round and went to see for myself as I was yet to witness the needle going over half!
Sure enough it's creeping up. As you start to accelerate the needle rises, and then drops back down to half on the gauge when you slow down and come to idle, as if it is having the opposite effect of air cooling. Very, very strange, I have seen nothing like it, it went as far as the first red marker. Got it back to his house, unscrewed the expansion cap expecting a lot of steam from an overheating car, only to find there was no such drama. It was however happy to take another 2 litres of water! Drove it home with the radiator topped up and all is well once again.
Now I am left scratching my head, as is my mechanic. The cars starts fine, runs find, no lumpy idle, and pulls hard. In fact it's a terrific car on the motorway. BUT... it is using water, somewhere.
Any help gratefully received.

Headgasket/cracked head is possible. Failing waterpump is another.
Personally I'd put it into an auction - get rid. It's unlikely you're going to make anything on it but it might help limit the losses. It'll likely as not cost more to diagnose and fix than what you'll lose auctioning it.
