DIY: Check a cylinder head for warpage.

[@bradreichel3649]

I'm never going to be able to go out for Indian food again without thinking about this instructional. Lol. Thanks!

[@barenekid9695]

Only problem being a Good straight edge Costs as much if not more than having a machine shop resurface the head.

[@fedor7695]

Well I just got mine for like 30$ off Amazon. The resurface at the shop will be 200$+ each

[@braydinjones6301]

As long as that isn’t warped more than .004 inches ur fine

[@bigron503]

Mines is so I can i just buy a new gasket or I gotta buy that whole block

[@EliteNK]

@@bigron503 new head

[@aarongiggers66]

Do you have to lay the straight edge all the way across?

[@BellyUpFishGarage]

The more area you can cover the better. It makes for a more accurate check.

[@derekkchung]

When a head is warped, it is like a banana, that means the cam bore also warped? If u shave off the gasket side surface to make it flat, the cam bore still not straight, am I right? U do not want a cam bending and rotating. Too much resistance and it will weaken the camshaft. The only way is to use heat to straighten the whole head and that is expensive process, am I right? With that being said, to what extent we can resurface (skim) the head without a concern of cam bore not straight? 0.002"?? To what extent we should not even bother fixing? over 0.008? (...for a 4 cylinder head.)

[@BellyUpFishGarage]

No, I don’t believe that’s correct. Just because the head warps doesn’t mean the cam will warp. The cams are steel, the heads are aluminum. I don’t know the maximum allowed shave of a cylinder head, although there are published numbers and a lot of heads have indicators on the head that will disappear if they’re shaved too far.

[@derekkchung]

Cam bore, not camshaft

[@BellyUpFishGarage]

My apologies. I read your comment late last night. I’d think it would depend on how bad the head warped. I’ve never had any issues with cam bind on a warped head, but that definitely doesn’t mean it’s not possible. On this B18B1 head, the max allowable milling of a head is around 0.040”, as best I remember.

[@MohammedSeid-m6x]

plis why to use double gasket after reface

[@rialtogamer]

Any update, did it end up working for you?

[@BellyUpFishGarage]

Yeh, this head (knock on wood) has been fine.

[@renediaz4164]

If this happens to an engine, do l have to change piston rings, rod bearings, water pump and head gasket set?

[@BellyUpFishGarage]

No, no, might as well, definitely.

[@renediaz4164]

@@BellyUpFishGarage ok. I got lot to change then. Costly for sure

[@BellyUpFishGarage]

@@renediaz4164 You can do it for less than $250 I think.

[@danielcruzrodriguez1444]

Them are some expensive straight edge thingys

[@BellyUpFishGarage]

They’re definitely not giving them away, are they?

[@jaisonserrao3383]

Do anyone konw abut bespergauge

[@adrianjbm76]

What mesurement is the feeler gage and what is the max you can support

[@BellyUpFishGarage]

2 thou is what I was using. Max will be based on engine you're working on.

[@u.s.a.198]

Thanks!

[@maximolotov]

those who can dismantle it will not benefit from your video. Those who can already know it

[@BellyUpFishGarage]

I disagree. Thanks for watching.

[@blank8800]

Well I'm actually watching this now because I haven't personally check for warpage, usually I just send these to the machinist and just assemble the finished product

[@RichLifeStories]

I am not a mechanic but I do know how to dismantle it. I do NOT know how to check if a head is wrapped. So I appreciate this gentleman for posting an essential video.

[@LogiDude]

@@RichLifeStories agreed! I can get the head off but I wanted to check to see if its warped BEFORE I send it off to the shop. Idk if the car just blew the gasket or if the head is REAL bad...
