I am building an engine from scratch and i cant find a sump that will fit over my integral balance shaft/ oil pump. there is a pipe that curls round from what looks like the dip stick hole, what does this do? do i need it? because if i take this off my sump fits perfectly :roll:
also i hav no oil squirters :cry: i tried to fit sum off an old 2.5 tdi but wont fit, what engines have the same ones as the 2.0 PD?
does anyone have a water hose diagram of an ALH so i know what im doing?
i heard that the water pumps go on these and when they do they mess everything up, can you get after market ones that are more reliable?

I have no idea what you are having issues with on the oil pump and balance shaft... aren't you using the oem one?
as far as the alh having issues with the water pumps thats true but usually only after 100k. you could always cut it out and use an electric pump if you wished...
for your oil squirters use 2.0l pd ones. they will work fine.
PS what are you trying to do? Have you seen my build thread? Chears kyle

The problem, at least in the UK, was the water pumps had plastic impellors, this was/is a problem on all the 4 cylinder models.
GSF sell a waterpump with the metal impellor, its cheaper, and i've used at least 2 now with no problems, they are cheaper aswell

i will purchase a pump from GSF then, thanx.
the oil pump/balance shaft is just one big thing, there is a bendy metal pipe about 6 inches long that the dip stick goes down, i cant make it fit with the only sump that is available to me. can i just live without it or will it not get the right dip stick reading?
was just wondering if oil squirters off anything else wud fit to save me buying them :roll:

ive come up with an idea. my mate works at a MR2 tuning company he tells me that people convert from hydraulic tappits to solid lifters for power gain because the hydraulic tappits are spungey and valuable valve lift is lost especialy at high revs.
how hard would it be to convert an ALH head to solid lifter?
how do i get it just right so it doesnt tap like ***?
ive got a spare 1.6 solid lifter head to use for spares should i use the springs and buckets from this?
is there any sutch solid lifter valves that will fit straight in to a ALH?
also a head specialist tells me that porting a turbo engine wont make any differance to power, getting rid of the 90degree bend from inlet to head might though, can anyone back this up?

For your head questions what you need is a cam, and a good porting. Also go for heavier valve springs if you plan on running things up at higher rpms. As far as hydro no hydro? I dont know about noise but I decided to stick with the hydros for now... I am not asking to have that much more lift where I can't run with them. BUT you can get parts from Rosten perfromance. Geir will take care of you, tell him I sent you. AND tell your head guy that 10-15hp has been seen with head porting for the tdi engine! This is on more modified cars but it is still worth it. Mainly to reduce egts and smoke though.
On the intake. I have no proof but I agree that reducing that angle to say 50 degrees from 90 would make for some drastic flow reductions!

well i was going to run an AAZ cam, i hear they giv you a bit more lift.
i didnt think mechanical lifters wer that noisey, maybe i was wrong.
i want sum serious power out of this engine, i dont mind thinking outside the box.
getting barings that can take 500bhp and ARP everything, because i only started with a block every single nut and bolt has been purchaced seperatly, only the highest grade steel will do. now im not sure what to do about a turbo/supercharger. need sum ideas, how can i get 350bhp? will a GT20 do or should i go bigger?
does anyone know how much power 2.0 ASV rods can take before they bend?

i have had a few gas engines with mechanical lifters (shimes and buckets)
and i like them for high rpm and if the oil gets a bit to hot ,no ratels,
But for a diesel 6000 rpm max good oil +pump+oil cooler , I dont think there is any need for mechanical lifters
as for turbo gt 22 for a min , or gt 28 , you going to run NOS and LPG ?
what lb ft can a pd crank take ? you may have to brace the mains :wink:
