Engine recondition Christchurch

stompin · Post by **stompin** » Mon Apr 23, 2007 4:40 pm

Hey guys

just wondering if some one could point me in the right direction. The vx has a cracked head and some very small cracks in the pistons, so its time for a rebuild or new engine, Id rather fix it properly than just slap a new head on it.

Who in christchurch do you guys suggest i take it too for an engine rebuild? (vx is down in the southern lakes atm)

Im thinking im better off to get it rebuild than slapping a second hand engine into it? The rest of the truck is mint the autos been reconditioned, panels are straight and the interiors mint.

Also how much is a new are wreckers asking for radiators apparently it needs recorded too?

Thanks in advance

Brad.

Sorry cant help with rebuild

but if you get hold of George at http://www.trademe.co.nz/Members/Listin ... ber=121869 i bet you he can do a radiator for you better than you could get down there :lol:

Cylinder Head Specialists in Sydenham are good, they do race engine heads.
I'm pretty sure they do diesels as well. Or try mace engineering

one more question..... any one happened to have a cylinder head for a land cruiser?

what engine is it ? I went & had a look at a few engine builders/machinists around chch , did'nt like some of their attitudes " its just an average commercial diesel engine, why would you want to spend money on it & doing it up " , etc - then came across the ideal one that are more into quality machining & have vast knowledge on latest engine building techniques , they are called "Coombs" - think they are on St asph Rd near fitzgerald Rd , i will be gettn my machine work done there .

Don't know many in Ch-Ch, but called into The Auto Shop (23 Waller Tce) to query about a trans cooler for my VX. Quoted $330 + GST & Fitting $120+. Seems reasonable :?:

He does radiators as well, and said he does a lot of work for Peter Munros.

Others may have a different opinion on the pricing/work etc

Ok so theres a small amount of work been done on the truck so far.

Pistons came out, throw them in an acid tank found out that 3 had some pretty serious cracks on them but the bore is fine, so $550 latter i got a new set. Genuine new toyota cylinder head $900. So new head, new pistons, new rings, some new bearings, and along with the other crap that gets done.

Injectors have been sent away to get cleaned and flow tested, but what about the injector pump? do i need to get that recod/replaced?

if the injector pump fails will it lead to catistrophic problems?

The only thing that will be "catastrophic" if your injector pump craps out is the loss of fuel to the engine. No major engine damage unless it is incorrectly timed and run like this for some time. :wink:

so do u recon i should just get it done or wait?

If you know your timing is right wait, and if you do anything major to get more power out of it do it then.

This is a no harm no foul diesels can run leaner and all they do is loose power (you will notice :shock:

) but most likley it will drop the fuel back to the tank when left on angles and will have to crank a bit (draw the fuel up to the pump again) when it starts getting work, this is when I would look at it (as it would piss me off).

what piston cracked? 2 or 3? is there any evidence of anything hitting it any bent valves? you may want to check as I have seen a tiny amount of water do this to the top of a diesel piston (swallowed while hot). (not mine I go Petrol and pay for it

hey,

what i believe happened, was the radiator cracked, got so hot the head cracked, then the pistons crackd? but i can only assume as i am not the one who blew it up. Got new pistons, head, bearings, valves and shit nothing was bent so nothing had connected. The cracks were right accross on 3 pistons i am unsure which ones they were, maybe 4&5 i think.. (with 1 been at the firewall)

so if it runs lean it wont detonate like a petrol engine from running lean?, this is my first diesel truck as ive been bought up with petrol trucks..

Its just to do the pump is another 1000 roughtly i think..

Diesels are not Knock inhibited they do not change their timing if they knock, the compression and heat from the glow plugs initially and the block after it is warm is what causes detonation, less diesel less compression, less power. You do get a slight heat increase but not much on a diesel they run hot anyway.

Diesel engines have been pretty somple designs and are only now starting to get more technical they were originaly designed to run on peanut oil the problem being the oil had to be heated to get thinner for delivery and if left on fuel lines it went solid. This is why you can get used oil from fish and chip shop's filter it and put it in the diesel engine, it needs heat still to thin it and a few other tricks (dual fuel lines start on diesel and change over when warm and oil fuel and oil lines are heated) worked on the direct injected 40 HP tractor

and a 2lt surf (I had to try it)

The pump will drop the fuel back to the tank when on angles (nose up and left for an hour or so) or you will have to manualy pump the pressure up to the engine to get it to go (if left a couple of day's in the sun after a good drive) when it needs work, if you look for more power look at the pump then. You should also notice the difference in power too. I would leave the pump till you have more funds.

the flip side of living down here... I know it will cost me a poooload more to get it done down here rather than getting it done in christchurch now while its all apart... The joys of living in a tourist town where you pay more for everything.

Apprently my truck should be ready friday!
