Not debating the name of it, just what it doesn't do..... Regards, Andrew.

I tried to explain that earlier in this thread or maybe another thread. No one listening! There's an experiment you can do in your freezer. Fill a bottle with water and put a small hole in it. It will still expand. Regards, Andrew.

STart at the beginning mate, all will become apparent!:icon_bigg Regards, Andrew.

Quick update: 400kms on and all is well with the car. Cooling system holding pressure, no coolant use, no weird noises, performance still what it was(both power and fuel consumption). So I think it's O.K for now...phew!:bigthumb: Will post if anything else changes, but man these things are...

Would you consider these engines noisier in the valvetrain area than a modern hydraulic lashed engine? The rest of the engine is so quiet the valvetrain realy stands out. Not that it's abnormally loud, I guess the advances in hydraulic lash and NVH design really show on these older, cam over...

I'd get it resurfaced. You don't want to be reprofiling metal with lapping, just removing machine marks. Those low spots you have remaining are just a litlle to unnerving for me, it would always be in teh back of my mind. Oh, and use another machine shop. And tell them light skim and do it...

I am going to be mounting a large external trans cooler soon, and I usually mount them to radiators for airflow at low speeds/heavy traffic. Do you think there would be an advantage to mounting a trans cooler in front of the intercooler, and having a large puller fan behind the intercooler...

Thanks IJ, that saves a long and possibly fruitless search through some cardboard boxes! Regards, Andrew.

Copper is one additive in Aluminium. There are other metals/additives I can't remember right now, will have to dig out a text book. It should be noted that pure aluminium is very soft and not really good for too much! Most of the metals alloyed with aluminium are to impart a particular...

Thanks for that info IJ, that tested is kind of a Rockwell hardness tester? I broke down today and bought a combustion gas leak tester, did the test twice (once when warmed up, once after a 5 min run) and came back negative, so I am pretty relieved at this point! So now EVERY test says...

Compressions were all good when checked after the event, and head stud torques were all still O>K. I haven't done a leak down test, but I am not losing coolant or getting too much pressure in cooling system. No fumes from crankcase breather either, so blowby has not radicaly increased...

As some would be aware through other posts, my engine with a fresh head gasket and ARP head studs had a big overheat due to a popped welch plug. Well, it's been two weeks, and the residual symptoms appear to be none! That's right, so far, th eengine that got so hot it MELTED the plug leads...

Starter is out! Friggin yay!:boink: Hammered the crap out of a cheapo 13mm socket I bought just for this purpose, I threw it away with the nut. Getting the alternator off allowed me access with my 24" breaker bar, and that, combined with jamming a ring spanner on the end of the bolt, got the...

Yeah, that nut head is as rounded as I've ever seen a nut! Got some damn torque on the bolt too..... I am going to pull the alternator tomorrow evening and just have a leisurely go at that bolt with a decent 1/2" socket and a FBH! I don't need to tell you guys how a stuck bolt in a difficult...

Yeah the alternator removal is a great idea, I will definitely try that! I have the extensions to do it too. I haven't even looked at teh car today, I am letting it sit and rot!:evil2: Nah, just calming down for a few days. I don't want to go in there and lose my temper, nothing will be...

A photo of a plug from this engine: What do people think of it? I reckon it looks OK considering, at least it hasn't melted or gotten too hot, which is a bit strange. I wonder if the ECU dumps fuel into teh engine when it gets too hot? Regards, Andrew.

I can get a wrench in there, but I can't get leverage on the damn thing. That is the issue. At least with a torch, you can get in there, heat up the nut and oxidise it, no leverage required for that, and nothing close by to burn either, nearest wiring is several inches away, and that unplugs...

Yep! Let's see...two hours work, with Toyota's wonderfully complicated wiring running all over and through the intake, plus vacuum plumbing and various cooling lines or five minutes with an oxy to carefully knock the nut/bolt off. Tough choice. An oxy torch can be controlled very nicely to get...

Ummm, re read my post. The nut is fucked.:nono: Knocking a socket onto it is not an option, due to the fact you CAN'T GET A HAMMER IN THERE. Never mind the bolt is on ridiculously tight. I have decent tools, thanks for assuming I don't. I have a selection of 1/2" 12pt sockets, 3/8" 12 point...

Hi, Tried to remove my starter earlier to get at a welch/freeze/core plug from underneath, the top nut is rounded to buggery! There is NO WAY I am removing the intake manifold again to get in there!:cry: Anyone got any cool suggestions on how to get a hold on it? Can't really get a hold...
