im buying a car thats had a Blowen head gasket, heads been removed. Whats involved in putting the new head gasket back on and putting the head back on? what should the head be torqued to? and how do i time the engine? its a Gen II 3S-GE.

Any Help is much appreciated.

Cheers

If you've never done anything like this before I'd seriously reccomend you buy a service repair manual.
First thing I suggest you do is find out why the HG blew in the 1st place and rectify it, ie. fans not working, bad water pump, radiator or whatever.
Second thing obviously is buy a new headgasket and new head bolts, waterpump, other gaskets from someone like Mr Revhead
To time the engine the cam lobes on no. 1 piston need to face outwards at 90 degrees towards the manifolds and the crank set at 0 degrees BTDC
It's also probably a good idea to get the head checked at an engine rebuilders for any warpage it may have incurred and remove all the gasket remains from the block before torquing the head back down.

oh ok, so when i have no.1 piston a TDC the exhaust cam lobes should face the exhaust manifold and the intake lobes should face the intake manifold?

i will buy a service manual tomorow

Is it possible to put a engine back in within a day? i never took it out but i kinda know what im doing, done a few 4age swaps before.
