GASRB6

Thanks guys I will give it a go. :bash: Appreciate the help. :y:

My 87 hatchs' interior fan only has 2 of 4 speeds working. 1 and 2 don't work but 3 and 4 do ? A/C is still activated on 1 and 2 but the fan dosen't switch on at all. Any ideas that may help me to fix this ? :bash: GASRB6

Update : Turned out to be the air conditioner fan belt. It had delaminated with around 4 inches missing on the inside of the belt. At idle it was just noticeable but moving it would expand and hit the alternator fans hence sounding like a knock. So I changed the belt and all was good. Got new tyres and clutch 3 weeks ago and the little 87 rolla hatch is purring like a kitten. Also got new hubcaps, woohoo. Thanks for all your input. Long live the rolla. Dingo.

Oil pressure light hasn't come on. Oil, coolant and all ancilaries are fine. :wink: Piston slap could be a real possibility. The motor is breathing quite heavily from the oil cap when running. The sound seems to be coming from the combustion chamber. Looks like it's tear down time for the old girl. :lolcry: Fingers crossed it's not too costly. Thanks for all the replies. Dingo.

Sounds like a knock, and it's quite loud. Not pinging. Dingo.

I have an 87 4A-c powered, 5 speed rolla hatchback. Yesteday while driving home the motor developed a loud knock. Wondered if anyone has had this happen and what the prob turned out to be. It gets faster and louder as the revs increase. Fingers crossed it aint a rebuild. Coolants fine, oils clean so i've ruled out head gasket. I think it could be one of two things : 1. Big end bearing 2. Water pump (bearing) All comments welcome. Dingo.
