Check those valve guides quickly, Pop check! Tech tip

Appreciate that man, thank you

[@scottsarver779]

Really appreciate you posting this. Have to check valve guides and had no idea how other than a wiggle test. Thanks!

[@gtpsleeper9]

Thanks so much for this video explanation of a quick valve guide check method!

[@3dprintingdentist599]

Just wanted to say, your video was very informative. The popping sound that the valve makes helped me out! My intake made the nice pop and the exhaust did not. Got the new valve guide in and it makes the pop noise.

[@cuttersperformance]

Simple but it works 👍

[@cliffweinan3907]

Nice practical test

[@alifrosli3894]

very good idea on testing the condition of the valve guide

[@julianlangdon3456]

Super video thanks, that Head's very different to my Volkswagen BMD but the principles are clear & relevant

[@williamstidham2163]

No pop, it’s a flop, That’s a lot of wiggle In those 2 valves, I hope mine has a good vacuum on the valves and no wiggles, Great true information, Thanks 😊

Fantastic video, great info thanks

Instead of pulling it out fast. You can spray the valve stem with a little WD40, insert it, put you finger over the hole as you did and slightly pull the valve out. You should feel a little suction on your finger.

Nice! This is a really good idea. Thanks for sharing it.

Would worn valve guide's burn oil when starting up and acceleration from a dead stop ? My stupid self put worn out 882 heads on my sbc 355 new aluminum heads are coming tomorrow compression is within 10% off each other 140 and 130 psi

[@cuttersperformance]

Yep that can be worn guides or valve seals causing that. But that compression is certainly on the low side so maybe try a leak down test to see where your compression is going

[@bk-yg9yw]

@@cuttersperformance compression is low due to the 882 heads being 76cc chambers I just rebuilt the engine

[@cuttersperformance]

Ahh ok, does it have a decent cam aswell? My boosted engines with approx 8.5:1 will usually have around 145 to 155 psi cold after break in

How can someone check for leaky valve guides if the guide housing is cracked?? Top of spring seat location of the neck. I know they’re pressed in but can it leak oil into the chamber/port??

[@amjedmurshed6887]

Thanks alot

[@BlueCollarCriminal]

This method baffles me I have some play in my guides but they all still pop from what I can tell. Sill have to remove a couple seals but the ones I notice have the most play still pop. Non of them are nearly as bad as the ones in the video as far as play so maybe that’s why I’m not noticing much. The exhaust valves make a quieter pop noise compared to the intake side with the head I’m working on I wonder if that means just the exhaust side ones need replacing but I’ll probably just replace them all.

[@cuttersperformance]

Make sure there's no oil or valve seal. A good guide you'll actually feel the suction on your finger tip before the pop. As shown in the video, a semi worn guide will have a slight pop but not alot of suction. It's just a quick check but actually fairly accurate in terms of determining if you'll need guides or liners

[@markopolo7651]

Are you supposed to do this with oil on the stems or dry?

[@cuttersperformance]

Dry or just very lightly lubed

[@rajeevv969]

nice bro ☺️

[@natedog9383]

Is it typically expensive to replace valve guides?

[@cuttersperformance]

They can be, especially if they are not a press in guide. Depends on your local machine shop prices

[@natedog9383]

@@cuttersperformance I'm trying to gauge my finances accordingly, since I'm getting my m62tu completely rebuilt :D. hopefully it will be reasonable since the valve stem guides are brass, and they appear to be replacable. I hope!

[@BlueCollarCriminal]

@@cuttersperformance why would a non press guide replacement cost more than a press in?

[@screwsinabell]

@@BlueCollarCriminal I'm sure you found an answer long ago, but in case anyone else is wondering: Short answer: it requires way more machinist labor time than a simple press out & in operation. More detail: If you have valve guides that are bored into the head casting (like with the AMC 258, for example), installing press-in guides requires exact centering to bore out the existing guides (which can be labor intensive because the guides themselves are likely out of round to the point where getting the exact center will be easier said than done). After that, the bores will need to be reamed to reach an exact diameter to accommodate the appropriate press fit of the new guides that will be going in to replace them.

My car smokes only at cold start.and it now consume oil there is a blue smoke on cold start at 2000+ rpm what would be the problem

[@cuttersperformance]

Does it give a good shot of blue smoke at cold start up? Could be valve seals

[@qazisajid9119]

@@cuttersperformance yes only on at first acceleration after that its quite normal i changed its valve seals but after some time it begin to burn oil

@@qazisajid9119 what engine is it?

[@kevinwest3689]

This wouldn't work for me. It can be off, and still pop. I am allergic to good enough. I feel that # good enough, is why it's having the problem in the first place. My guess is that the seats were not Properly Aligned with the guides. I have the tools to properly measure. But not to align and cut seats. So instead of saving 30 minutes and what ever the price. I'll have the Machinist do it. And hopefully THAT guy Knows what he's doing. I've had bad results with- good enough- from a machine shop as well. Powell machine in..North Carolina ? That guy is on point. Tell him Kevin west sent you 👍✌️
