engine ticking noise

Valve lifter or "tappet."

"Costly" is relative. $1000 at a m> i have a 1988 944 turbo s with 103,000miles on it.

annoying ticking noise.

the engine is cold. the car has an excellent service record and has been run on fully synthetic engine oil for around the last 25,000 miles.

could this be costly to sort?

My 86 944 also has something that sounds like it could be related to this...if I wait til summer to do it, will it hurt the car? Is this a problem that could leave me on the side of the road?

mechanic. could this be costly to sort?

You need to figure out what it is. Before something shreads, fills your engine with metal shavings and you're rebuilding an engine you didn't need to.

Bad lifters that can be safely ignored tick at start-up but quiet down after a m> My 86 944 also has something that sounds like it could be related to

This would be me. After it runs for a few moments the sound goes away. Actually, about two months went by (October-November) where I didn't hear the sound at all, and about the middle of December it came back. Its not like a tick tick tick, its more like a plasticy raddle? I will take it in non the less.

Just curious, does it happen at a certain RPM?
