If the engine is high mileage then tappets get a tad clogged and different temperatures affect them.....next oil change use engine flush then a good oil, should sort it (i assume the service was done at a garage?)
If it doesn't the options are live with it, strip them and clean them or replace!
im aware of the clogging lifters but why this happens from my work constantly and not from home confuses me. isnt the oil ive got pretty good?? (service sheet says mobil 1 was previous oil but it was a bit too thin getting for milage)
get the engine up to temp and remove the oil cap and keep a rag handy, you should get a load oil come out, or there should be alot being thrown about by the cams, or fit a gauge
Two reasions why they should be noisy.
1. tappers and oil paths clogged and they get not enough oil == noisy. Use engine flash, some diesel or even I heard some people use automatic transmission oil to clean the oils paths.
2. high milage causes the tappets wear out and tolerances, gap increase. As a result the tappets loose oil== noisy. In this case the cure would be to use thicker oils like 15-50 and 20-50. Don't use cheap 20-50 oil though.
Try 1 before an oil change and use 2 to change the oil.
Oil's thicker when cold so would fill any wear in the tappets....thinner when warmer including sitting in hot sun.....some residue in the tappets can drain out resulting in temporary tapping..also if there is a prob with the tappets the lifters can wear as well doubling the problem
updated.... cams were throwing about a fair bit of oil inside the engine.. and every 20seconds or so a little was thrown out onto rocker (very little "dabs" but it got everywhere)
that means theres no real oil flow problems? or is there more checks i can do without fitting a gauge?
