Re: Tappet Noise - Exactly How To Fix It?
OK, here we go again.
The tappets sometimes clatter because they are gummed up with old oil or dirt from oil that hasn't been changed regularly enough.
This method is not guaranteed to work, but is cheaper than buying a pair of tappets far less than a full set. It also does not require the engine to be dismantled in any way.
Follow the method carefully, there are no short cuts.
1, Go and buy two oil filters and a gallon of diesel.
2, Run the engine until warm, switch it off.
3, Drain the oil and remove the filter.
4, Refit the drain plug, fit one of the new filters.
5, Put the diesel in the oil filler. Yup, thats right, fill the sump with diesel. No honest, thats exactly what I mean. Its a thin oil, do not panic.
6, Start the car, DO NOT USE THE ACCELERATOR AT ALL.
7, Run the car, you may increase the engine speed to a fast idle. No more than slightly above idle. About 10 - 15 minutes will do it.
8, Drain the diesel from the sump, have a look at how dirty it is. Diesel contains detergents. Remove the oil filter.
9, Let it all drip out, do not rush.
10, When its all out, refit the sump plug and fit your second filter.
11, Fil with good quality 10/40 or 15/40 oil.
12, Start and drive. If the tappets are quieter, all well and good. If not, then either live with the noise or replace them.
