Cold Start Engine Noises

Hey Guys,

I’m sure the majority of you are aware of this, sometimes when you cold start the engine you get a loud noise coming from the engine until it’s heated up to operating temperature. I’ve read about it and most people have dismissed it saying it won’t do any harm and it’s normal. It’s a painful noise to hear from an engine, I read something about piston slap and valve train. Is there any way to remedy this noise? Would a block heater help?

Thank you for reading

 

I wouldnt call the piston slap loud, more like a ticking. Is that the noise you are talking about?

 

you mean the ticking? cause shim/bucket valve trains tick

 

Yes like a ticking

 

Taco tick, even when warm can still be heard but it think that's the lifters

 

I’ve also asked this question and was told it’s the VVT-I warming up. It’s so loud when it’s cold that it sounds like a valve is going bad or something, right?

 

Yes exactly, it gave me a lot of concern before I researched into it

 

Yeah totally normal. It's the engines way of saying hello.

 

it satisfies my diesel fantasy

 

Uh I have no such issue.

 

probably cause your valve shims are too tight and your engine is going to explode

 

tight = quiet and shims cant be tight, only clearance can

 

which are used to adjust clearance, that's where I was going but eh

 

oh so what you meant is "your valve clearance is to tight" and as I said, tight valves (min/no clearance) are quiet.

 

pretty much

 

oh alright, i dont believe these motors have shims either, you have to order the bucket in specific thickness as the bucket is the shim. . lol

 

well the shim is set inside the bucket so you could technically still argue that is has shims, no?

 

Lol, you dick

 

when you call it a "shim" you give it Independence and after that it starts thinking it can vote and how it wants equality etc.. slippery slope

 

ok chief
