Swapping engines

[Senatorpack@xxxx]

Aside from stop light to stop light acceleration, there isn't any benefit 
to swapping the PRV V-6 engine out of the DMC. The DeLorean engine is 
reliable and easy to maintain. The myth is that the PRV in the DeLorean is a 
POS...not true. 

Renault Formula One Racing won many races around the world with PRV 
racing variant. That engine redlined at 10,000 RPM and made over 490 HP.

The early PRV engines in the Volvo 260s from the mid '70s had issues 
surrounding oil flow delivery around the cams. PRV factory engineers over in 
France corrected the issue long before the DMC ever made it into production.

Another myth surrounds the BOSCH K-Jetronic fuel injection in the 
DeLorean PRV engine. The fuel system is reliable and maintenance free, 
however it will fail if the car is not driven...plain and simple. Think about 
those beautiful supermodels...they get pissed off, temperamental, demanding, 
and cranky if you quit paying attention to them...if you find one that 
isn't...give me her name. 

The DeLorean car BOSCH fuel system does not like long term storage and 
will act the same way. Long term, incorrect storage will wreak havoc on ANY 
car. 

E.G. The same BOSCH fuel injection system on the DeLorean is also on late 
model Lamborghini Countach...twice over. Two fuel distributors, two cold 
start injectors, two accumulators etc. The Lamborghini, a very fast, 
unrefined, unreliable, pain in the ass to drive and operate, and they usually 
have very low miles on the odometer. There is an owner near me with 90,000 
miles on his Countach, however he has taken the effort to drive the car 
almost everyday. He explained that most of the Lambo car owners let them sit 
for long periods without starting them or adding a fuel stabilizer. The same 
problems on the Countach list are asked here on the DML. The issue arises 
from deteriorated fuel system from improper long term storage.

The PRV engine is a strong motor. The DeLorean specialists can clarify 
any of your questions about high mileage capabilities. To date I do not 
remember reading anywhere on this list or in DeLorean World magazine about 
engine failure, aside from overheating the engine and warping the heads & 
damaging the headgaskets...that is a direct result of a damaged cooling 
system (bad hoses, belts, radiator, waterpump) and not changing the oil every 
3,000 miles with a correct filter.

The no start issues, incorrect idle, etc., the multitude of problems 
about DeLorean engine reliability on this DML list is attributed to incorrect 
repair, incorrect parts, incorrect long term storage, incorrect methods of 
awakening a car back to life after long term storage, etc., and not 
maintaining the car properly...unfortunately many owners are driving around 
with an incorrect oil filter, and a worn out, 21 year old, corroded, cooling 
system with duct tape keeping the hoses together. Not worry because the 
DeLorean specialists have just about every part for the DeLorean available.

Here are some web pages over in Europe devoted to the PRV engine:

Here you can upgrade the engine's performance to suit your needs...if that is 
what you're after.

The second page has many links to different suppliers and high 
performance dealers.

To summarize, the PRV engine issues are not some inherent design flaws or 
poor planning by the Renault engineers...the owners issues you read & hear 
about here on the DML arise from lack of proper maintenance & a general 
unfamiliarity with the engine operation and basic maintenance requirements. 

If you spend some time reading about the engine (reviewing your budget & 
finances as well) and read how to maintain the car properly, buying the 
correct parts from a DeLorean specialist will keep a smile on your face.
