MWMike Posted July 26, 2014 Share Posted July 26, 2014 My MW oil consumption has started to climb, and I am considering refurbishing the cylinder head and fitting new rings after a bore-hone, so I have a couple of questions...... Are valve guides still available for this beast, or is it a case of making some? I heard a story, although it may be bull-deposit, that a set of Transit engine valve guide seals work on the truck and are a better option than the feeble felt washers supplied, if so, which transit engine? Is it possible to slip the pistons out with the engine in the truck? (Accessing the crank via the sump, obviously) and do they pop out upwards? ( In my 1938 minx you have to insert from the sump side which means crank out!) I don't really want her off the road over the summer but she is getting to be a bit of an oil junkie, and is always looking for her next 30 SAE "fix"! ...oh! Cylinder pressure readings are all consistent around 185-200 psi. in anticipation... mike Quote Link to comment Share on other sites More sharing options...

The good ones will restore compression if low and lower oil consumption. Get you thru summer for winter rebuild!! Quote Link to comment Share on other sites More sharing options...

MWMike Posted July 28, 2014 Author Share Posted July 28, 2014 I was at Foxhall saturday with a 10cwt trailer in tow, with my blue Hillman staff car next to it............mike Quote Link to comment Share on other sites More sharing options...
No Signals Posted July 28, 2014 Share Posted July 28, 2014 Make sure the guides on offer match in design the ones you have. When I had an MW I bought a set and they turned out to not match/fit. Had to buy a second set.:-( Quote Link to comment Share on other sites More sharing options...

Had to buy a second set.:-( Good point , I had to measure my exhaust valves, Norman told me there are two sizes..........standard , and the desert modification which was slightly bigger. Mine had the modification done ? , the interesting thing is while stripping the paint off we came across two shades of sand/dark beige (desert camo) . Been in touch with the RLC before Christmas but not had anything back from them . I did have the measurements of the two sizes written down , but can't find the damn bit of paper .

MWMike Posted July 30, 2014 Author Share Posted July 30, 2014 Thanks guys, Norman from bygone bedfords has contacted me and explained all the possible sizes and shapes of the guides and valves and as long as they are available I am confident that I can rebuild the head if necessary....I just have to make the decision to do it- before the Arnhem XXX corps run, or after!
