Excessive tappet noise on cold start-up
My 2005 Crossfire makes quite a lot of tappet noise on start-up from cold. The noise gradually goes away after about 5 mins (once warmed up) but is this noise normal on the 3.2 V6 engine? Its very noticeable even though my car only has only covered 34,000 miles and is regularly serviced (including oil change).
Any advice would be welcome. |

Any advice would be welcome. Had similar problem, Oil change and driving it a little more helped. Cheers. |
Re: Excessive tappet noise on cold start-up
It's all good in da hood... just pretend your driving a porsche. :D I still haven't figured it out myself nor have many MBZ mechanics. I've heard people say its related to the timing gear sprocket, it needs to get oiled before the noise goes away, then another theory where the silencing rubber coating on the sprocket has worn away. also if the oil sprayers to the sprocket gets plugged it will make the noise. Then there is the issue of tolerance in the cylinder bore, I know many late model chevy motors with piston slap issues until fully warmed up, none of which are harmful to the engines life. So I just live with it. it only last a couple seconds and then its gone. But I doubt it's related to the valve train.
Also there is a check valve on the driver's side compartment that make a loud ticking sound, completely normal. |

Re: Excessive tappet noise on cold start-up
I read your post and thought I should reply.
About 10 years ago I worked for a Chrysler dealership. One of the problems some motors with aluminum block encountered was a thing called piston slap. This would occur at cold start up then quiet down once warm. My understanding is that until the rings warmed and expanded, the piston was slapping within the cylinder. This piston slap sounded more like a knock knock than the click click of a tappet. A bent rod can increase the contact distance and cause tappet noise. A motor which has been run low on oil and ran hot can develop noisy tappets among a list of other things. I'm no mechanic... |
Re: Excessive tappet noise on cold start-up
Since it has only 34k is the 3/36 warranty still good? If so get it into the dealer soon, so you can verify the existance of the problem before the warranty expires. There are may possibilities, from chain tensioners, to valve train to piston slap, none of which should be occuring at 34k. If you bought it used, did you have the factory warranty transferred?

Re: Excessive tappet noise on cold start-up
all the m112 engines make this noise, check around the mbz forums, it's normal though it is a little too fast to sound like piston slap.

https://www.crossfireforum.org/forum...earchid=305651 https://www.crossfireforum.org/forum...earchid=305657 Searchid's are not kept for very long by the BB system, so the links die after a short while. One of the hardest things for users to know to search is what keywords will quickly land them on the prior posts. What do you you search for when you don't know exactly what it is called that you are searching for? |
Re: Excessive tappet noise on cold start-up
Thanks for the advice guys. I'll check out some of the things you suggested. The engine is peachy when warmed up and I've no other complaints but the cold tapping seems out of place on an engine which has been well maintained, fairly low mileage and hasn't been abused or raced.
As for HDDP's 'advice', well, we all have a bad day I guess. Put it down to male PMS! (only kidding). This was the first time I'd posted a thread on your site, and I don't use forums normally (I find the telephone usually works better and is quicker!), but it's cool. I'll definietly be back however so thanks again for helping a fellow Xfire enthusiast from across the pond. :cool: Cheers, Ecosse_Cross |

Mine gets loud once and a while when it's cold. I just give it a good thrashing and it goes away for a while.

Re: Excessive tappet noise on cold start-up
clicking ticking clatter
usually the lifters, when the oil reaches them.. pumped up the sound goes away , but 5 min time frame wow ! |

Mine had a loud tick not the normal benz sound, new engine is in and I hope to get it back in a few days...

Oh and HDDP needs to chill the frick out, grow up bro. Maybe he feels better about himself now, or feels like a cool guy, who knows what that guys problem is. |
Re: Excessive tappet noise on cold start-up
the tappet noise is not from the valve-train, there are a couple things that can make the noise, one is the little electric check valve on the drivers side, the exhaust manifold, timing chain sprocket is not getting oil from the oil sprayer, or the fuel injectors.
You could pick up an automotive stethoscope and trace it out. |
Re: Excessive tappet noise on cold start-up
Thanks for the advice guys, I'll check out the possible causes you mentioned. Good news is that the faint/occasional smell of burning oil in the cabin has been cured - a gasket has been replaced under warranty (cam-cover vent gasket I think it was).

Re: Excessive tappet noise on cold start-up
My 2005 with 15k miles and newly changed oil is now 'tapping' erratically at start up. After reading all threads...maybe overfilled? Or valve lifter clatter?
Is there any sort of additive to add to synthetic oil that may reduce this problem without ruining something or other? Old school there were 'valve noise reducers' available at cheapo auto stores. |

They usually do more harm than good. You should double check the work that was done. Check the oil filter housing to see if it's leaking. That's the most common place for leaks on these cars. Check the oil that was placed in the engine. If you did the change yourself, you should know what the oil was you put in. If you brought it to a shop, you will need to call them, and ask them what they put in your car. After that, you will need to figure out if it really is the lifters making noise on your car, or if it is actually the fuel injectors you are hearing. They are very loud on these cars. Typically, the lifters are only heard for about a second or two on a cold start, then they quiet down after they are pumped full of oil again. An engine stethoscope would be very helpful in tracking down where the noise is centered at. BC,. |

Re: Excessive tappet noise on cold start-up
Although not really related, the search function at crossfire forum does not work. Many times I have searched like today, looking for "cold start die" and get one not very good match, but when I take same search to google I get many more answers from this site. Why does this sites search work so poorly?

It is not too good that's for sure, it just searches for words not phrases I think. So it is best to use less words even one word if possible. Cold and start got a lot of hits, adding die would get a lot of useless hits. So pick your words carefully. Knowledge of former posts helps a lot but that is not much help to new users. I find that I can whittle down searches quite well if I can remember the original poster and then use one word. But I have read most posts since 2006 that interested me. |

I'll try again, but for clarifications sake I did not use quotation marks, I learned not to do that except in certain situations.
Thanks Rick |

Disregard. I just saw the dates. |

Re: Excessive tappet noise on cold start-up
[QUOTE] My crossfire has about 150,000. It has a tick sound at startup, but goes away after about 2 minutes. If I drive it to work and it sits out in the sun all day, it does not make the ticking sound at startup. I tried using 2quart of Lucas oil stabilizer with my oil. It quites it down a lot. I will try the heavy duty oil stabilizer in the summer. I’m using the synthetic stuff now. |

A little clarification here. First, the thread is 6 years old. Two, the talk of lifters and tappets does not apply here. This engine has needle bearing rockers that ride directly on the overhead cams, no lifters, no tappets, it has a finish like a fine swiss watch. What they may be taking as tappet noise is probably the clearance between the rockers and cams. So you say that there are no hydraulic lifters? What about the ones in the rocker arms? If they fail then you can get noise due to excessive clearsnce. |

No, I don't think there are any. The rocker roller end rides on the cam, the other end contacts the valve stem. Somebody correct me if I'm wrong. https://cimg7.ibsrv.net/gimg/www.cro...2619b1af9f.png |
