How a Machine Shop Checks and Resurfaces a Cylinder Head

We Resurface the Cylinder Head to correct the warpage, test the valves for leaks, check the head for cracks and clean all gasket surfaces. We take off .008' on the head.

Wish i had people like this work on my engine issue.

It's cool to see a knowledgeable and skilled young lady in a predominantly male field.

Great video. There is a lot of prepping to this job of "milling". I didn't know that. My Honda Civic head (2005 LX 1.7L) is having this done to it right now.

That was really cool! Never seen the actual process. I've got my Dodge 3.9l torn down which the heads need to be plained, block boarded to .30 and hopefully the crank will just need polishing and not have to get it grinded .10 of an inch.

Great informative post(I really loved the classic style workshop training manual info-graphics), and great to see a lassie in the machine shop too.
Best wishes from Scotland.

Erm Honing is not to smoothen the surface of the cylinder walls but rather to create a cross -hatch pattern to retain the motor oil and to try prevent blow-by.

Thanks for posting this enjoyable and informative video!

Really appreciate the video, this is a process I'm about to do myself and wasn't sure exactly what would happen at the machine shop.

The Delta Custom Tools pressure testing stand, good Canadian made tool👍. They make them right here in my area. Good vid🍻

Great video! I'm having this done to my 97 Saturn SC2 right now.

Why would you go through all that trouble and expense to remove and surface the head and not go ahead and machine the valves and seats ? Sure it cost some more $$ but the labor to get to that point and back is way more.

OLÁ. Não é necessário usar "lâmina de folga". Inclinando a "régua de Precisão", inclinando e usando a quina, um lado luz e outro na sombra verás a planicidade que pode lhe indicar a qualidade do serviço da retificadora. Se usares a quina totalmente oposta poderás confirmar a deformação e até constatar se a "régua" não está deformada. Para não deformar a "régua" ela deve ser guardada dependurada. Um lembrete: Os blocos de alumínio podem deformar mais que os cabeçotes. O que realmente interessa é a soma das deformações. ABRAÇOS Roberto Udo Krapf

If it was that warped, i would have definitely done a valve job, check the springs and changed the valve seal. It definitely got overheated.

If the head was warped that much did you check the camshaft journal alignment? When the head warps up in the center so does the camshaft journals.

good video. Great idea power washing it.

If decking blocks and heads and cutting valve seats was all you could find on youtube i’d be fine with that😀

[pcbondart]

ok, the head warped .008 or so, aren't the cam bushings out by that much too? What about them??

[Sirmellowman]

the book says the max you can take of is 8 but ive had customers say just do it when they had .025 plus needed to be taken off and it was totally fine. yeah the compression might go up a little but they engine ran totally fine. you can safely take upwards of 15 all day long without any issue what so ever. and that goes for pretty much anything out there.

Thats good machine shop probably not all do all just do little of it
