Help, lifters are sounding!

[josephmotors]

The lifters tick for approx. 15 seconds on a cold (below 32 F) startup. Is this normal? Do the lifters need replacing? What can i do to prevent this? Thanks in advance. :help :help :help

what weight oil are you using?

[josephmotors]

I was using mobil one sythetic 15w50 for the last 3-4000 miles. The lifters were ticking on cold startups, so I replaced my oil yesterday with Pentosin (http://www.crpindustries.com/pentosin.htm) Synthetic 5w40. It came in 5 liter containers and i only bought one so i had to add 2 quarts of conventional Valvoline 10w40. The lifters still sounded this morning.

Your next oil change, try running mobil 1 0W40 and see if that helps.

I tried using a different oil weight when I had this problem and I got a CEL for my knock sensor 4-6 cyl's. Have you had that problem when you switched weights? Did it in my old 2.5 motor as well.

Just a lil fyi

My 93 325is is doing the same thing.I,ve switched oil brands and weights and it did not help.The strange thing is when the engine is hot it won,t tick none.

do a search, the topic has been covered before. our cars tend to do this when theres also not enough oil
