[DML] Re: Another DMC newbie (Alex's Engine)

["content22207" <brobertson@xxxxxxxxxxxx>]

People, please -- a little civility goes a long way.

This car's engine came up for discussion last spring -- see Message
#39625 and thread preceding/following. Alex also sent me some engine
pics off List at that time. My conclusion: everything north of the
heads, except for hard steel injector lines, is consistent with stock
DeLo, not Renault Z7 series:
- Two piece fuel/air mixture unit (separate throttle plate assembly,
which means the throttle plates themselves probably have deceleration
valves)
- Idle speed microswitch and throttle plate trigger
- Cast iron fuel distributor (versus aluminum)
- Lambda
- PCV through cold start tube, not U pipes
- Shear head balancing screws
- 066 series CPR
- No fuel dampener
In fact lines to the cold start valve and CPR are flouroelastometric,
not steel. Only things visibly not DeLo are the steel injector lines
themselves (which I hasten to point out are much easier to work with
and around than flouroelastometric).

Someone needs to do a compression test on Alex's engine to determine
if the block itself has European or North American pistons. If that
person is feeling especially industrious, he or she can remove the
timing chain cover and look at part numbers stamped into the ends of
the camshafts to determine if the cylinders are 2.7 or 2.8 liter.

What is this allure with "DeLo" engines anyway? With the exception of:
- Missing ignition distributor counterweight
- Proprietary water pump and crankshaft belt pulleys
- Missing smog pump
- Different A/C compressor & alternator
- Proprietary exhaust manifolds? (No air injection)
there is absolutely no difference between a "DeLo" PRV and Volvo B28F.
That *WAS* DMC's intention of using an engine already certified for US
emissions on such short notice...
