They were just a spare set i had laying around, the set i'm using is still in the head...
Here's how everything stands:
ARP studs installed (with the lube), new water pipe bolted on and gasketed up - ready for the head to go on! There was ONE snag though - the water pump housing uses two locating dowels, one at the top, one at the bottom (you can see them in the picture), and the bolts go through the middle of them. Sods law stepped in on my behalf - first bolt i decided to put in was the lower dowel bolt. Head sheared off as if the damn thing were made of cheese!
*cue lots of swearing, tools being flung into the courtyard, face turning red etc*
I thought - okay, as the bolt thread has just been tapped and the bolt ran through a die seconds before, it shouldn't be seized. The bolt just goes right the way through the housing, so i could feel it protruding. Tried unscrewing it from behind and it worked for about a turn, then i couldn't get enough torque on it. Again, cue swearing. I don't have any reverse drillbits or anything suitable to remove it. So, i considered leaving the bolt in there and just using some loctite sealant on the gasket around the dowel. But no, i ruled that out as being a bit cletus - and i'm a neat freak. Overengineered or not, i was determined to get this bastard thing out!
Phoned my mate ed, who explained that the dowels can be removed from the water pump housing (front timing plate) and you can buy spares. With the dowel out of the way, i'd have just enough protrusion to get a set of vice grips on the bolt and back it out that way. Time for a screwdriver and a hammer - sliced halfway through the dowel, and grabbed the lot with the vice grips - the dowel had mashed itself into the bolt thread still in there, and pulled it out when i turned the mangled dowel peg - WOOHOO! IT'S FREE & OUT!
Thankfully, and most unlike Toyota, the parts are still available (16185-70010, if you wanted to know
), and only €2.44 each + VAT @ 19.6% - i'll buy two, just in case, and use new bolts from the hardware store, cause i've had quite enough of shit breaking, it's why i've been anal about buying new studs for the exhaust side of things - you just KNOW they'll turn to cheese and shear!
However i *STILL* need to get the damn shims...
