I was curious what the "Beam Camshaft Caps" were. It is very different design of the heads. I found a manual for a 4G9 Mitsubishi engine. I thought that it might be at least somewhat useful to you. Here is the link:

Thanks for this HunterD

Mine is extremely similar to that shown on page 11A-8-2a (DOHC-GDI)

where it looks like the rockers work off the camshafts....

Very difficult to figure the oil ways allowing the oil IN to the rocker area....

Roger -

Looking thru my hard disk it turns out I have 6G7 series workshop manual which has lubrication diagrams in it for 2 and 4 cam engines. Also a section on the GDI engine. Attached are the lubrication diagrams.

Send me a private message with your email address and I will email you the manual.

In the process of cleaning my rockers... whilst still on the vehicle

The air Intake manifold is off as well as the rocker covers.... I want to clean out as much oil residue as I can from the rocker area without taking the cylinder heads off ( I know I should but I am trying to avoid this).... I should say that the sump is also off.

I thought I could move the rockers and clean them and then clean the rockers area of the cylinder head.

The issue I have is that the cylinder head incorporates holes for the spark plugs but particularly air holes for the air intake manifold?.

What problems am I facing getting any residue oil or sludge or anything down these air holes...

I did read that with the sump off I could clean that rocker area and try and drain everything whilst draining through the sump area 12v cummins intake manifold. I may even try some sort of diesel or other solvent wash with compressed air and a fine nozzle on the rockers area?

Any of you guys have an idea how to protect these holes?

Any help is as always very much appreciated

Thanks

To clean the rocker area without contaminating the air holes or spark plug wells, first, plug these holes securely with rags or rubber stoppers. Use diesel or a solvent to clean the rockers, letting the residue drain through the open sump. When using compressed air, direct it away from the holes to avoid pushing debris into them. Once cleaned, ensure all residue is drained and remove the plugs or rags before reassembling. Double-check for cleanliness to avoid any blockage or contamination.
