TUD5
What is a turbo?
I should introduce myself first, I am Martin and I live in Scotland (we say things like aye, eh and aboot. Ken?)
Having issues starting my old IDI engined car. It's tiny 4 cylinder, 93CI TU5 series diesel built by PSA. Covered about 150,000 miles so not a huge amount.
anyways, it's very hard to start from cold (especially at 32F or less) Sometimes cranking for 15 seconds before it fires (after a 20 second pre-heat). When it fires, it starts and runs on all 4 smoothly. there's no spluttering - I'll check the resistance of the glowplugs but I don't think they'll be at fault. It's had a new battery and the battery is good under load.
However, recently, I have changed the cylinder head gasket and the cylinder head itself. My old head had a sticking inlet valve and a cracked pre-combustion chamber on another cylinder. H.G was also spewing oil down the side of the block.
So, cleaned the deck of the block, fitted a new gasket and head. It's got tappets and shims so I spent a few hours measuring all the clearances and swapping shims about - using some from the old head too) and they are all just about in tolerance.
When I re-assembled everything. All earthing points and exposed electrical posts were cleaned. The car turns over very fast compared to before. I'm not sure if this is compression related, or because I cleaned all the terminals on the starter etc.
I haven't changed the fuel filter, although I did drain the gooey watery **** from it - I will change that soon anyway.
tldr; - because I think the problem is here
Now, Fuel pump. It's a Bosch VE style pump. I bled the fuel lines BUT I have noticed that the fuel going into the pump (I have clear hose just coming out of the fuel filter housing so I can see, as the rest of the pipe is black rubber pipe) is bubble free, but on the lines coming out (they are clear silicone pipes) it's all frothy. any ideas why that might be? has to be air getting in there? The car certainly has more power than before, I can get it to 100mph and it's 4 seconds faster from 0-60
The pump is timed correctly, I've retarded it and advanced it on the pulley with no effect on starting.
When the engine is hot, it starts within a few turns (about 0.5 seconds or less) on the starter.
Cheers for any help
Remember, if it's from Scotland, it's Whisky. ;p
