How I rebuild a car engine cylinder head. Blown head gasket, burnt valve, etc. Pt 1 of 3 - REMIX

Head Rebuild: 4 - 6 hours ($200 / $450 / $2,300)
WARNING: The cam cover and cylinder head are a machined pair and one can not be replaced without the other. Do NOT damage the cam cover, then try to find another cam cover to replace the one you damaged. Get another head with it's matching cover.
This video explains the process that I take when preparing to rebuild the head.

This video will show you how to rebuild a car motor cylinder head. You can pay a shop to do this for you or purchase a head from a national supplier, but it will likely cost you between $400 and $750. You can do it yourself for as little as $125.
This head come off of a Volvo S70 but should be the same for many heads.

Checking the flatness with cast level from home depot that has +- 1/8" flatness. If you really that concern, you need precision flatness ruler or granite top. It's all overkill. I installed heads warped like bananas and they flattened right down with bolts. Never a problem. There are so many bolts all around each cylinder. It will seal and hold for years. Same goes for reusing original bolts. Never a problem and I did dozen of heads. It's better to have warped smooth surface then shitty machined head that was cut too fast and left bunch of grooves (cutter marks). This head flatness is an old myth that won't go away. Dates back to old iron heads that did not flex. Shops still make money and keep this myth going. You can have 1/8" gap in aluminum head and the bolt will pull it down with little effort (by spinning the socket by hand)

Interesting. Not a risk I'm willing to take.

I wish i had this knowledge 6 months ago, but I'm so glad you've made a video on this!

[@RobertDIY]

Actually I just remixed this video that has been up since 8/13/14. :/

[@AnotherBandNameLater]

@@RobertDIY Okay, I watched those videos to get my 96 850 R fixed!

Excellent video. Thanks for posting. This is the first time I’ve heard of putting the gasket sealer on with a roller. I’m working on my 2005 Volvo xc70. I need to take the camshaft cover off to clean the coolant channels. Can I get away with leaving the timing belt on, pulling the cam cover, cleaning it up then putting it back on?

[@RobertDIY]

There are no coolant channels under the cam cover.

Sorry, I know you've explained in multiple videos about the VVT cars, but I really want to make sure I get it right and don't mess anything up: So to rebuild my head (2000 V70R), Sorry if this is a stupid question, but if I will be taking the head off and apart, do I need to set timing (marks aligned on the front) before I take the VVT hub and sprocket off, or is that just when putting them back on? I know I need to use the cam locking tool on the back of the engine, but is that the only necessary tool, there's a kit here on ipd. couldn't include the link, but it also has: "rear camshaft lock tool, starter/crankshaft lock tool, camshaft retaining tool to hold cams to upper carrier, and upper carrier release and install tool" Do you think I would need to get that whole kit or only the cam locking tool? Thanks Robert, your videos are super helpful

[@RobertDIY]

You need to keep the lifters in order. You also need the locking tool that holds the back of the cams.

[@Lexiberian]

Hey! You mentioned at 9:03 that broken lobes are not a big deal, can the machine shop fix them? Thanks Robert

[@RobertDIY]

that's a question for the machine shop. I'm sure some would try, other's would not.

[@Gordon302]

Generally, Volvo heads don't need to be milled down. It is however, important that use new, torque-to-yield head bolts when replacing the head gasket.

[@RobertDIY]

Huh? If it overheated and warped, it will need to be milled. 🤷🏾‍♂️
