I did not change them myself. My mechanic did that.
Because the head has been rebuild twice, the valve depth is pretty much, leaving little space for shims.
Scored some spare shims at the junk yard last monday, when I picked the nozzles up.
At the machine shop they made the shims fit between the cam and valves.
Unbelievable what difference it is. She fires right up and revolution is much nicer. Boost building up is getting better too.

We agreed to push another 5.000 kms, check valves again and than install the Forge actuator.

On a side note, some squiking noise came from the rear wheel this morning. Inspection showed us that one of the handbrake pads was loose on one end... sigh, always something with old cars. :cry:

Antenna mast broke. Tried an cheap Ali one, but the plastic tooth piece does not fit. Bummer, was really cheap.
I am trying the dealer now.

Oh well, the rectifier died too (again *sigh*). Installed an rebuilded alternator now.

Okay, here is the deal. Compression is gone again, after another 3.500 kms.
Checked valves, too thight again.
Hmmm, wait, that is not good.
Checked the internet and it appeared that some Ferrea valves cannot handle the 3S head... sigh. Guess what is in my car.
I should have checked this before buying, but that is too late now. I contacted the importer in Europe and let see what is coming out.

Contacted the Toyota dealer too. Intake valves are deliverable, exhaust not. About 50 euro's each, ex VAT.

So, the head has to come off again. Was there nobody on this forum who could warn me :-)

You seem to have very bad luck, my sympathies. This is the first I've heard of issues with any of the valves available for this engine. Skimming the start of that thread though it sounds like the issue lies more with the Engel springs he used?

You should read the entire discussion on MR2. Then you find out it is in the valves.
My engine is equipped too with the engle springs. But, they are there since 2002 and since 2005 with 264 HKS cams and stock valves. So, no problems with this combo in 18 years and about 100.000 kms.

Perhaps I should find me some good used Toyota valves.

Strange, the dealer is not giving new part numbers if they fit from an other car. So, when I asked for my own valves, they don't have/give other options who might fit. Result: do it yourself:

Second gen 3S valves:
In = 13711-88362 = ± 55 euro ex vat.
Ex = 13715-88361 = not deliverable
Third gen:
In = 13711-88460 = not deliverable.
Ex = 13715-88480 = ± 65 euro ex vat.
Fourth gen:
In =13711-88580 = ± 35 euro ex vat.
Ex = 13715-88480 = same as third gen.
Delivery time: approx four weeks, they think...!!

Well, since 3S valves almost never crash, we decided to trace a set of good used valves and install those.
Valves are probably here by wednesday. Head gasket is ordered, so hopefully no long down time.
