what manual recommend for yanmar head gasket repair

[inquiztr]

I think my yanmar engine has a blown head gasket. It is the 2 QM 20 yanmar engine. What service manual would you recommend I buy to learn how to do this job.
I have downloaded a few pdfs online of service manuals that have great breakdown of the engine, but never details the steps of properly doing this job.

Thanks

I've got a 2QM20. Right now I'm looking at my Seloc Repair Manual #7400 for Yanmar 1975-98 engines. Page Chapter 7- Page 10 is "Cylinder Head Removal and Installation for QM Engines". Yey! The manual has lots of other great stuff a DIY'er can use for engine maintenance and repair (hopefully not.)

Here's a link to Seloc's website: http://www.selocmarine.com/ . Use the drop down to input your enginne. Looks like there is an online version. Hardcopies are less expensive at places like Amazon.

Of course Yanmar makes a QM repair manual, but harder to find. I've got one of those also. Its better on some points, but the Seloc is better on others.

Good luck!
