urgent td5 head advice please!!!

**Rosscoe68** · 3rd February 2011, 09:39 AM

i must admit, on my first TD5 D2 when i got it, it ran at 86-88 then after i fixed the head and all new hoses and thermostat it now runs at 91-93. pretty much the same as you now face. i put it down to the cooling system not being right beforehand, not the other way round.

i am just going through the same process on the 2nd car, so will wait and see the out come on it. it ran at 87-88. will see how it all comes after head is fixed.

i was contemplating getting silly and port matching the heads and and manifolds and getting the valve seats smoothed for flow , but then i realised its a deisel and i am a bit older now and don't really need to waste money on that stuff anymore

I must be as silly as you Rosscoe, as i was thinking of one of those gadgets that lets the computer run more boost

. But perhaps i should just let it all settle in for a while first. Thanks for the help mate.

Matchporting the turbo to manifold isn't a bad idea though. The size difference is quite significant. Exhaust port at the turbo is quite a bit smaller.
Intake to head won't really make any noticeable difference unless its as badly matched as the V8's are but never seen the porting on the intake on a TD5.
Shortening the runners would make a difference to turbolag however.
Biggest problem is they are only a 2 valve per cylinder setup...

i don't have a problem with 2 valves per cylinder, i reckon it should have about another liter of engine capacity to push a 2 tonne vehicle though, even turboed

i know i know get an isuzu

Temps
when not working on the freeway mine runs at 84. Small hill puts it anywhere up to 87. When working hard and hills it can reach 91. I have tested it repeatedly.

dang
mine goes to 93-94 going up perth hills if its is hot outside

Just a quick op date. Drove 800ks towing a trailer 400 of those had a series 3, 6 cyl ute on the trailer and the td5 never missed a beat. The ambiant temp was at 38 deg, the car temp rose to 95 at one stage but mostly sat about 88. Very happy with the out come.

I would like to thank every one who had some imput through the head gasket job. Its greatly appreciated.

Cheers Jim.
