4 cyl big block oil pumps - how many versions? FAQ added p2. Updated p4.

PG lump has 1 squirter per cylinder, I have two stripped ones in the garage, also they are different to ABF ones, thats all I remember.

 

In saying all this, I've omitted to mention the 16v intermediate shaft pulley is also smaller, meaning the 16v pump runs faster too! But I've read that this is mainly relevant to lower rpms

 

Brian,

Just a quick Q, something which came across my desk. Even though the AEB casting numbers are the same, is the driveshaft the same and the pick up pipe?

Reason I ask is the part nos differ: 058 115 105 C (AEB) vs 051 115 105A (ABF). Could relate to other items on it, with a common casting. Sumps the same? Edit: this bit confirmed elsewhere as different oil pick up pipe.

Anyway, this means it's clear the AEB 1.8T ran 36mm gears. 20 small hydraulic buckets to look after... Does the AEB have oil squirters? I've never seen inside one.

 

Ill check when Im in workshop The pickup Def is not the same, Im talking just the pump. and its p/n number.

 

Just spotted this linked on the GTI Engineering thread:


It has the large intermediate shaft wheel, suggesting same as the 8v GTI motor. Assuming the valves are solid tappet, I wonder if it has oil squirters? Presumably not, since really this is an EG Mk1 Golf GTI 1600 motor, with a 4-valve head dropped on it. Even though it does have its own dedicated engine code, it's not necessarily different.

 

Does anyone know what holds the squirters back until 1 bar? Where's the restriction? Just curious - can't get my head around that!

 

I think it's a ball valve with a spring behind it?

 

Ah, makes sense! Whereabouts is it located? Somewhere inserted into the block with a proper blank punched in to keep it there?

 

internally in all 4 bore squiters Chris..

 

Sure - any pics or anything? There must be an existing gallery being tapped, surely?

I "don't believe" Oettinger used that first. They seem to do all VWs R&D!

 

Pictures


Ball pressure valve can clearly be seen located in the end of the banjo bolt.

 

No squirter in oettinger block chris unfortunately
Mechanic tappet
The oettinger engine have a specific oil pump shaft and a spacer plate to cope
With the deeper sump

I m trying to find some way to get squirter I was thinking having them fitted on the rods
Carrillo offer this option

 

Hi

If you are after Oil pumps for the 8V I think the order is as this:

1.6 GTI EG Solid tappers small pump
1.8 GTI ?? Hydraulic tappers medium pump
1.8 G60 PG Hydraulic tappers biggest pump for 8V

I used the G60 Oilpump in my 1.6 GTI EG with Turbo

After reading the Oilpump is bigger in the ABF I might get one for my KR with Turbo

 

Everything so far here

 

In a write up of the Golf engine evolution, the 1.8 16v is stated as having been fitted with a pump "from the Turbo Diesel, giving 15 per cent more flow."

I can't quite figure this out, as it implies the DX/EV ran a pump with gears < 30mm high.

Putting it here in case more info turns up.

 

If anybody ever bought a TSR 1.8L 16v bored and stroked to 2L they never refitted the oil squirters , due to clearance issues with the Crank.

i always remember Satty Singh buying one of their engines and having issues.

 

Could that be down to the intermediate shaft pulley being smaller on the 16v and therefore spinning faster than the 2:1 ratio of the 8v engines?

 

It is dificult to keep track for me.

If I would like a bigger pump in a KR what do I do.

Also should we change the plug?

 

AEB oil pump.

Yes. of course.

 

Is 2.0 16v and 2.0 8v intermediate shaft end gears the same?
