Oil Problem (Windsor 302)
I have a Fairlane ZD 302 Windsor motor.
It has now done 150,000 miles (approx 240000kms), still the original motor(all numbers match).
I drive this car on a regular basis
I had been topping up the oil (about 500ml) every 2 to 3 weeks as it used to go down to about 1/2 of the Safe indicator on the dipstick.
It doesn't blow smoke in the mornings,when I'm driving or when I accelerate.
But I have noticed the tapets are quite noicy when the oil goes to that level.
Pardon my ignorance as I am a novice to mechanics but Is this normal for a windsor motor at that mileage to use a bit of oil
Someone suggested I use Penrite oil 25/70 thickness and now it only needs a top up every month or so but the tapets are still a little noicy and they get worse when the oil drops to that level
Is it normal for the tapets to be so noicy?
I dont believe it needs new rings, but then again I might be wrong.
Could it be the valve stem seals or is it losing oil from somewhere else.
Any help would be appreciated
