Hi, Back in the day, in the UK, I was a mechanic on Volvo F88/F10's, moved to Vancouver Canada in 1980 and worked for Western Mack. After a 15 year stint in aviation I'm back wrenching on buses for our city Transit. I'm a hobbiest restorer of planes, trucks and buses... my current project is a bumper-bumper resto on a 1956 Scenicruiser Coach with an 8V71. I'm sure there is a Mack restorer in the PA area that is doing one for a customer, anyone know him? I have an itch for a cabover, maybe the F88 never got out of my system, just for car/truck shows and bobtailing around as a private truck.. so I've been looking around for a year or so and while a Kenworth K100E Aerodyne has a certain appeal the condition vs price is outrageous. So, a recent advert for a CH613 locally got me interested and some research piqued my interest. I never saw these when at Mack in the early 80's so had to start asking around and heard nothing negative. I need advice... while I can figure out the blatently obvious (40 years of busted knuckles does that) I need input on what to look for... so, what is the achilles heel of the MH??? 1989 sleeper, E9 V8 500HP with recent turbo, rebuilt Mack 12spd, rebuilt Mack axles, air-ride rear suspension, 500,000km's.... But, there's a downside... the owner found a small amount of coolant in the oil when draining... so he pulled the pan and presurised the coolant... but no sign of any leaks... So... how good is the V8????? any inherent problems? has he found a common issue with cracked heads - gaskets - liner seals??? do I ignore it or run away??? I would like to buy locally, time is short to go jetting around the country and not cost effective at this price range... not many cabovers left on this side of the country and importing to Canada CAN be a PITA if things go sideways at the border... please throw anything at me... I've been reading here for a while and you seem to be a reasonable bunch of Mack gearheads.. thanks Sean
