Hi All,
I recently bought a 1979 rubber-bumpered MGB GT, with a newly reconditioned engine. This was bought from a reputable MG specialist - and I will check these things with them too - but was wondering what other peoples opinions were.
When I bought the car (a week ago) it seemed to idle fine (at about 800 revs). The oil pressure always seemed slightly lower than my previuos MGB, but generally sat between 50 and 75psi - so I didn't have any need to worry.
A few days after the purchase, it started to struggle when idling, and would quite often just die whilst stopped at lights. When 'struggling' the oil pressure would also drop to about 25-30psi. I also notice that any extra load on the battery (switch lights on etc) would be just one step too far ... and ... chug chug chug splutter ... splutter ... stop.
Thinking the idle speed was just set too I increased this to around 1000 revs (although, I note the haynes manual states 500rpm ... surely that's way too low?). Increasing to 1000 revs solved the stalling, and the oil pressure started to read 50psi idling, and between 50 or 75psi when under load.
Now, a few days later - all seems fine. But I have noticed occasionally when pulling up at lights, the idle speed seems fine - and yet the oil pressure drops down to that 25-30psi region.
I always believed anything
