yep ....it had me thinking a bit Bob ....so I flattened the pipe a bit in the middle and managed to eek out another mm so I now have 2mm clearance.....crankshaft scrapers run at a helluva lot less so I thinks I should be ok now ....have also welded the brace back on too.
Got a nice clean cylinder head to sort out now, so I gave the coil rail a good clean.... ca18det engines have a coil for each spark plug, and got that fitted then I moved on to re-fit my nice blue cam covers, also tried the plug cover but I think that might be painted the same red colour as my bodywork, got to start cleaning/painting all the pipework and ancillaries but it is nice to put something on the engine knowing that it ain't coming off again.
nice clean cams/bays
cam covers fitted
