Greg944 Posted 19February, 2012 Report Share Posted 19February, 2012 Hi all, New member to the forums, looking to buy a Porsche when I return home from overseas. I have two options: buy a 944 Turbo or S2 as a Daily or get a 911 as a toy or fun car/long term project I am still gathering information about which way to go and the comparative costs. In my research I have heard of the issues (some of them) with the 2.7lt cars, namely valve guides and head studs.... How widespread is the problem, what are the typical costs to resolve (or is it cheaper to transplant a 3.0 or 3.2lt engine) and is there anything else to be aware of with these era of 911? Many thanks in advance. Greg Link to comment Share on other sites More sharing options...
JustJames Posted 19February, 2012 Report Share Posted 19February, 2012 Hi Greg Are you referring to the Dilavar head studs? AFAIK, those were used from 1978-1989, i.e., SC 3.0 and Carrera 3.2 engines. If so, most of those cars will had their studs replaced by now, and for those that haven't a case can be made for them continuing to last if they have lasted this long. At Autohaus Hamilton we recently rebuilt a 1984 3.2 engine that still had the original Dilavar studs, but that was cause for some wonderment for our engine builder. The youngest 2.7 911 is now 35 years old. Any inherent weaknesses will have come to light and hopefully been resolved. As with any other car of this age, condition trumps everything, and a hefty history file will tell you what has been done on the car and when it was done. Transplanting an engine may ultimately reduce the value of a car if you ever come to re-sell it. Whether that is a concern depends on what the car costs you and whether re-sale value is a consideration for you. James Link to comment Share on other sites More sharing options...
jnr356 Posted 20February, 2012 Report Share Posted 20February, 2012 2.7 have a habit of pulling the studs out of the crankcase,this can be repaired with case savers or helicoils. valve guides,well any car can wear those out,but being aircooled they are prone to wear slightly quicker how much?,well how long is a piece of string,you won't know until it's pulled down,i do think though that if you intend to keep the car long term a top end rebuild is just a half job,for a bit of extra labour,bearings etc do the bottom end as well at least you know what you have then. all repairable and as previously stated an original engine is far more appealing(imo) best thing is to find a car with documented history,don't go on heresay,and then get a pre-purchase inspection done by a reputable porsche specialist good luck Link to comment Share on other sites More sharing options...
