Engine re-build

I suppose you have to ask yourself why the conrods were bend!!!!

Sounds nasty
Any idea why?
Do you need any torque settings? I can get them to you if you need them.
It is a good opportunity to have the valves re-seated and the head checked for warping.
Make sure the clamps on the little rubber elbow between the turbo and the block are nipped up tight (cooling system). They can leak if they are disturbed.
Good luck

Hi there,

make sure you replace front crank seal, timing belt/chain, check end float on oil pump if it is internal (if ext can be done anytime). check bore for wear, a hone or even rebore may be required, last thing you want is to put standard rings in, and find blow by once assembled.
Also check crank journals for wear, symetry, and get the conrods closed and honed, esp after you will be replacing 2 of them, may require machining and os bearings.
May want to replace thermostat, and while it is off I would be doing the head if not done recently, do it once, do it right esp if you plan keeping the car for some time.
Ensure you use loctite or similar on all conrod journal bolts, and on crank bearing cap bolts, and if internal, on the bolts holding the oil pump and pick up in place. Have seen bolts from these components come loose after a re-build as mechanic was lazy, and not very clever. Any failure of this kind can not only mean re-build again in near future, but very expensive re-build if hard parts are damaged.

Hope this helps,

Michael, The reason why the conrods were bent is that i was lazy and didn't check tha depth of a creek, and injested some water. The head was orignally done up after this and a new head gasket was put on, what i was told was that it was only that the gasket was sacraficed and the conrods would be ok. They turned out to be only bent by a very small amount. The pistons were only down by .3 and .5 of a mill.
Oskar, thanks for the offer, i got sick of asking for these of everyone, so i bought the td27 manual online for $40.
Swine Hunter, Thanks for the info some will be used, i have the pistons & conrods in at a local joint being looked over at the moment, and i have a friend in the bussiness sourcing all of the other parts that i will need.

The Water-pump assembly is available from Repco (and other sources) I believe. I think it is the same for a few Nissan models but I can't be sure. It may even be the same as the Pathy.
I got a second hand one from a wrecker who wanted to charge me $140 but I talked him down to $70. But that one is starting to go now so I may have been better value to by a new one. I'm not sure but I think others have bought non-genuine for $180 or so. (But I may be way out on that one) Worth a look around anyway.
Have you got the Haynes manual for the rest of the car?? (Repco)
