T25 engine swap 1.9 - Oil pressure light/buzzer!!! ARGGG!!!
Posted: 28 Jul 2006, 15:52
As some of you prolly know I blew a head bolt 2 weeks b4 bugjam. I payed someone to swap the engine for another and now I've been left with a legacy of problems and a pretty much unusable van.
Ive been given it back and its absolutely piddling water out but I'll have to trace and sort that out as he seems incapable!
But the biggest problem I have is the oil pressure light is contasntly flashing and the oil pressure buzzer constantly buzzing!!!! Basically as soon as you rev the engine (doesn't beep when first started) it starts to buzz and doesn't stop till the ignition is switched off.
I think he has wired things up wrong. There is a spade with nothing attached to it on the side of the dizzy and the wire from the oil pressure sender isn't connected to anything. When connecting to the only remaining wire (double plug) it makes no difference. I've tried different combinations on this plug but no change. I'll take some pics over the weekend to see if they can help.
The haynes manual is no good as most of the colour codes don't seem to match the diagram, but past experience of Haynes have never been happy ones!
Also I think the engine may be different. The new one is an early 1.9 engine and the one that dropped a stud a late 1.9, as its now MUCH slower. The water pipes needed changing over too and I believe that the late t25 had 2 oil pressure switches where as the current early engine only has one???. Anyone know what I need to do in this situation with the oil pressure switch? And wire(s) for the original late switches that are prolly the double plug left on the van?
Thanks in advance!
