Valve lash setting

[Mustardxf 29]

basically goes engine builder didn't give me the cam card. 
engine builder misplaced cam card

gave me a cam card that he thinks is mine

Problem: Cam card says its a HYD cam

~Engine builder said we were using a solid cam

~The motor definitely has solid lifters

 

Now is there a way I can Set the valve lash without a specified lash setting?

or should I go back to the builder and hassle him until I get the right card?

 

I remember the original cam card said .577'' lift and it was solid so shouldn't be to hard to find.

 

Reason being is my motor sounds a little tickity and It would be good to have them set right.

I reckon the best route would be to check them hot (and I mean really warmed up) and go from there. Ballpark figure would be 0.008" inlet and 0.012" exhaust. I don't know how an alloy head would change from hot to cold, maybe the lash gets bigger instead of smaller due to expansion in the alloy? Are you running lash caps?

[CHESTNUTXE 7,321]

what brand of cam is it ?

[Mustardxf2 310]

I don't think I'm running lash caps, it's not on the build sheet anyway.

 

It's a cam tech cam

[CHESTNUTXE 7,321]

small solids on the camtech website say around 15thou lash with the bigger ones .20 to .24 lash, there is no 577 lift on the solid cam page ?

If i don't know the spec i usually go .020" hot  is fairly safe for most . Alloy head and cast block usually change around .003 -.004" from cold to hot 

[Mustardxf2 310]

Yeah it's a custom grind chestnutxe

 

So I should try .020" hot and see how it goes?

[CHESTNUTXE 7,321]

solid's are usually a bit ticky arnt they guy's ? compard to hyd.

[Mustardxf2 310]

Yeah they are, but mine haven't been reset or checked after its first start up, everyone's always saying it's real ticky and loud so I just want to check them.

[ando76 4,354]

There is a bit of extra noise in the top end with a solid.  I set mine at .008&.012" cold on my solid crossflow engines that see a few revs.  Tighe recommend .020/.022 hot.  I'd go through and check them and if you find one that is way bigger than the others on the current lash it could be pointing towards an issue.  Hard to say but I would take note of the loose one and re-set and then check again after a bit more time. 

 

Just make sure that your rockers aren't hitting the rocker cover and causing the noise.  You should see some witness marks if they have been

[Mustardxf2 310]

I'll try get a video up so you's can hear it for yourselves,

 

I'm running a Aussiespeed cover so I hope they aren't hitting

sounds mean,i see what you mean ,what oil are you using ?

[gerg 10,871]

0.020" is very loose, that's half a millimetre! Maybe they want you to set it at that to allow for valve/seat bedding in and recession.

 

Rule-of-thumb says you lose half a degree in timing for every thou of lash you dial in.

[Mustardxf2 310]

Fuchs Titan formula 60

 

I run locked timing a 32 degrees could this be adding to the violent ticking as well?

Nah too much timing will show only under load. My clevo runs close to 40 at idle on a mild cam, loves it, runs smooth as custard.

[Mustardxf2 310]

Yeah that's what I thought.

 

So from the video does it sound a little loud to you or?

Sorry can't see it from my phone, I'll try it from the website later.

[Mustardxf2 310]

Oh not a problem.

 

Anyone else have some input?

just see how it go's for a while,might settle.

[ando76 4,354]

Very hard to tell from the video as only the last couple of seconds is near the engine. To me it sounds okay. I'd be checking for an extractor leak. If the lash is set properly then really there can't be an issue.

[slydog 7,873]

My solid roller is set @ 22 and 24th hot and the valve train is noisey for sure,but it's not a taxi engine it's a hot engine and there meant to be heard.

 

Here's mine on jack stands @ idle in gear and you can hear the valve train easily,but you don't hear that when you rev it

Alright after hearing yours sly I don't think I have much to worry about, I always knew that a solid engine is louder but after a couple of people have mentioned how Loud it is even after I've said its and solid combo had me wondering!

 

Here is another video Ando, that was after a cold start. https://vimeo.com/149700228

And what did they expect a stock taxi engine ??? Mine is a solid roller and it's noisey like a flat tappet but it's just how shit is. Been a 4 barrel car they idle alot choppier which amplifies the valve train noise too...Yous sounds stout IMO. I'd be happy with that.

 

Same engine but with a 750DP...no where near as smooth or civilized.

 

 

 

Just go enjoy it bro.You will know if anything is wrong.
