Big experiment, you need to change the petrol tank

You mean a DH ? VW did that too ……

Petrol WBX have a known weak link in the charge circuit as they age , the main wire from the alternator to the starter motor ( and thus to the battery ) rots internally , goes high resistance and eventually breaks down completely , meaning you have charge coming out of the alternator but not much ( ...

Sounds like they fitted a early DG , which didnt have the second oil pressure sender , which would be located between the water pump pulley and the top of the oil filter housing

Squirt some brake cleaner or WD40 on and around rather vac pipes and inlet manifold , if the revs rise there is a leak

How much pressure were you using ??
Is the oil missing of the dip stick?
You didnt bother to tell us what engine ? Oil cooler failed?

AGM is lead acid , Absorbent Glass Mat , it’ll be fine, although it may not charge as fully as a traditional wet plate battery , but no lead acid battery fully charges on an alternator anyway .

Too lean too much air ? Or possibly not running on all cylinders properly .

Sooty plugs, mixture too rich , have you checked the temp 2 sender is connected , not corroded connection ect
Temp2 controls the equivalent of the choke adjusting the mixture according to engine temp .
What state is the air filter in ? Blocked , oily ? Not enough air intake equals too rich

Morning
Yes i drove mine for some weeks without the entire set up while i was waiting for parts many years ago when such things were hard to get hold of , just be aware it will roll !!

Never had any issues with the cork gaskets ( fitted with a finger full of multipurpose grease) and original rocker covers .
Are your heads damaged where the gasket fits?

Honestly its “plug and play” you already have the old one out , plug it in and plush the switch into the hole .

Part number circled . The one you got new is for a t4 or a golf i think

Firstly ,


Secondly the headlight switch is age related , but you should be able to get the part number off the back of it .
