Engine Mounts & tilting twink
Posted: Mon Jan 01, 2007 1:34 pm
Hi - Happy New Year to all listers
I know this has been mentioned before and after having looked through som previous threads on the above matter- the details expereinced previously did not meet my enquiry.
I have just fitted new standard stock engine mounts to my engine and installed in the car and before bolting everthing back on- I trial fitted the bonnet and noted that the clearance was insufficent from the cam cover to the underside of the bonnet.
My question is :
What is average clearance between the underside of the carb manaifold studs and to the top of the footwell - mine is in the order of 50mm.?
Does any one know if they have had to swop the heater valve over with the temp sender unit as I have had to swop these over as this clashes with the passenger footwell. I am of the view that this makes no real difference to the efficency of the water circulation to & from the head to the heater matrix.(Unless Lotus water is holier than thou!!!!)?
Does the above mean that I have fitted the exhaust side mount the wrong way round with the 'u' shape bracket in the 'n' position. Meaning that if it fails the engine will drop rather than catch in the inverted 'u' position. I had it the other way originally and the cam cover was level!???
I am getting frustrated as there is no text in the manual that tells me what is correct and having looked at Brian Buckland's book the mounts used are those fitted to a spyder spaceframe chassis where the mounts are fitted to the chassis back to front and utilising the bespoke brackets from engine to mounts.
I have a spyder chassis but the sheet metal version that utilise the ford mounts purchased and fitted.
Some photos showing the correct positioning of mounts and extent of 'tilt'.would be useful
Secondly as I have installed a tubular 4-2-1 steel exhaust onto the engine while in situ and this was a real challenge as the tolerance between exhaust downpipe and top lip of chassis is at the moment about 3-5mm at a guess. I have not cut the top lip of the chassis for clearance as I note that has been done on Gordon Lund's Lotus book and not mentioned in Brian Buckland's book.
I know each Elan that came out the factory were never identical in fitment compared to modern day cars- but I would be grateful of some advice on the above as I am now nervous about completing my rebuild until the above points have been ironed out /corrected.
Thanks in advance for help and assistance.
