Oil Pressure Reading & Injectors


Recommended Posts

I was wondering if anyone could help me with the following two questions please?

 

Question 1). As we all know, the position of the oil pressure switch (1987 GTE coupe) just below the manifold is a pain in the rear end. Having had mine moved to the timing housing can somebody tell me if the oil pressure reading should be the same or will it differ slightly?

Question 2). Does anybody know someone/somewhere or if you can change the short hose crimped to the top of the standard injectors. Has anybody had it done and, if so, how successful was it?

 

Many thanks,

Steve.

The oil pressure reading will vary slightly as it will be reading from the pump and not the engine.

 

I have had my injectors reconditioned so it can be done but not sure what he used. For what it costs I would get them done.

Hi Danny,

Thanks for your quick reply. The reason I ask about the oil pressure is that, since my pressure switch was moved, my oil light comes on when revs drop below 1000rmp and the gauge reads just below one bar. I've changed switches but that makes no difference. For someone like me with limited mechanical knowledge it's a little disconcerting.

Re; injectors - did you have the hose replaced and who by? Two places I have approached, one being a Bosch Centre, said it can't be done which I find unlikely.

Hi 

I also moved my oil pressure sensor to the front and didn’t notice a difference with the reading. So may be something else going on. 
Herman changed the pipes on his injectors and it didn’t look that difficult.

If for some reason you don’t want to go through the whole post it’s on page 8

As far as fuel hose goes do the whole lot from/to the metal pipes on the wing, you can get it from here

get new clips too

Also get similar here

Since you’re sorting it out, get new seals & gaskets too, hardened rubber air leaks are a pain.

yes moving the pressure sensor doesnt make any difference. its still in the pressure side of the pump so should read the same.

and the hoses can be changed easily. they just cut and pull off.usually the end ring gets damaged unless your very carefull.

try not to mark the metal tube badly as it could cause leaks. new pipe just pushes on. no hose clamp needed but can be added for extra security. bosch didnt fit any originally .

Thanks for all the above info and the link to Herman's rebuild - a very good read. I will sort out replacement fuel pipe and get the injectors cleaned professionally now I know that can be done easily. As for the oil light coming on I am still stuck for answers. Pretty much everything that can be changed, adjusted, cleaned etc. has been done. I will get the pressure re-checked and, if all reads well, just put it down to an anomaly with my engine, very frustrating  😠.
