Heres a precautionary tale....one of WOE, that got a lot better.
Had some spare time at work, so pulled the intake pipework off the intercooler to the intake manifold. Bloody hell, the whole intake plenum was about 80 percent reduced with crud...turns out the EGR wasn't blocked, as a thought it was.
"No drama" I figure....long screwdriver, brake clean and a heap of rags got it as clean as i could without comppletely removing it. Took about an hour.
Go to start the car...CLUNK.
"Uhoh"......try again...Clunk, BANG, tappity, tappity, tap...kill it immediately.
"WTF?"...goo and gunk should compress, not harm anything, I reckon.
Next minor debacle...snap the bloody overflow off the radiator.
Right, thats it...get it flatbedded to a workshop, recommended to me by a mate.
Get it there....and it starts and runs perfectly. The flatbed ride must have dislodged whatever was oinging around, inside the cylinder.
Ten thousand tonnes of crud spewing out of the exhaust (which is what I expected...not the CLUNK)
So I figure "its here now...fix the radiator, drain and replace coolant, get a new fan and replace the viscous hub. While your at it, remove and retorque the crank bolt with new loctite"
The result....?
Original Viscous hub was stuffed, fan blades had small cracks and would have let go at some stage, the top radiator hose connection had already been snapped off by a previous owner, and the clamp was tensioned with a zip tie (didn't know this)
New coolant added, new radiator top tank, new hub and fan.
Crank bolt was removed, cleaned, loctited and re-torqued..so thats all good.
Car runs perfectly, Temp Guage about 10mm to the left of original position.
Glad it happened at work, not up in the hills with the kids, or on a beach below the high tide mark.
A cooked donk and 4 screaming kids (and a screaming Missus) would be my idea of hell.
EGR is NOW blocked, intercooler butterfly removed, intake cleaned, EGT and boost gauges plumbed...just have to wire them up.
Had 4 hours at Glasshouse today in some mud and some hill climbs...car runs perfectly.
Love it.
