Finally took the plunge :-)

Hiya guys. I have posted before but want to again what a fantastic forum. Its this forum which has persuaded me to take the plunge as you guys fill me with confidence.

Well what a car. If I knew the 964 was this good I would have bought one many moons ago. I thoroughly enjoyed my 190 mile drive back after my purchase today. I have owned a 2.7, 3.0Sc and 3.2 Carrera in the past but the 964 is a good blend of old and new. I finally went for the C2 coupe as I was a uncertain of the issues connected to the C4. Next I will be looking at a cup pipe and also replacing the air filter just to beef up the sound of the car.

I have though a few issues which I really need to address.
1. At idle the oil pressure reads between 1-2, then at 2000-3000rpm onwards the pressure rises to 4-5 which seems too high compared to my previous 911's. Is this normal.
2. Oil temperature rose from zero to only a quater and sat there all throughout the journey, is that ok. Rose a bit more when I got into local traffic when I got home.
3. Check oil when car warm and it had been over filled by about 5/6mm/ Is that going to be a problem
4. The heater stayed at warm throughout the journey and even when I adjuted the knob to cold this had no effect. Any advice?

Sorry for all my queries just want to sort them out and really enjoy the car.

Ray,

Welcome to the forum - and, more importantly, to 964 ownership!!

All too often we hear people putting down the 964 because it's not this or not that and it's so nice to hear someone praise it for what it IS.

To answer your points.

1. The oil pressure is fine. 1-2 on idle is good and 4-5 above 3000 rpm is exactly what it should be.
2. Oil temperature is typical and confirms the thermostat is working correctly. Rarely, if ever, will you see the temperature ris ebeyond hald way up the gauge.
3. I wouldn't get too excited about the oil being a little over the high mark. Ideally it would be better a little below full. You could always drain a little from the crankcase (not the tank) when the engine is cold. The chances are that the engine will use a little anyway (they are supposed to) so it's likely to remedy itself anyway.
4. The heater system is quite complex and can be difficult to diagnose. The main cabin fan stays on the slow speed in the early cars (even though switched to 0) and has a tendency to draw warm air through the heat exchanger regardless. The differenctial pressure flaps at the rear should divert most of it through the rear wheel wells and only then the temperature selector is moved off the blue dot should the rear blower come into action to open the pressure flaps. There are 5 servo motors at the rear of the luggage compartement (just in front of the windscreen) which control the air distribution and these commonly give problems and stop working so it's worth checking them out too.

The 964 is a great car and you'll find the learning curve steep. The 964 community is generally very technically savvy and really helpful and, if you haven't already done so I'd suggest to join the forums at www.911uk.com, www.rennlist.com and the Yahoo Group at http://uk.groups.yahoo.com/group/porsche964/. Owners from all over the World use those forums and the knowledge available is astounding. There are 964-specific meetings arranged from time to time too (we had 21 cars at last weekend's meeting near Leicester) so keep your eysy open for the next.

Best regards

Dave

PS. Just noticed your post on 911uk.com and Steve and Sundeep's replys. At least we're all telling the same story!!!
 
Dave thats brill. Very informative. I am trying to accumulate as much info as possible. As I have had a few 911's in the past i am not overly worried. These cars are pretty much pullet proof. The 964 is a very quick car and it really suprised me, on the way back seems to pick up speed with ease on the motorway.

I am delighted with my purchase and am looking to keep her for many years to come so really want to prep it and use it daily because its a shame to see such a car sat in the garage. The only reason why I sold my previous 911's were to funds property but as now we have bought a house for life there is no way in the world I will part with it.

Another question the area under the front wheel storage was a bit damp today and I noticed that the drain hiles were covered. I have unblocked them, im assuming they are there for a reason.
 
Ray,

The drain holes in the front luggage compartment should be fitted with small rubber "bungs" which allow water to drain out but not let water in. They often seem to be missing because I think they can easily get pulled out if the underneath gets scraped (grass fields etc.). They are called "Drain Tubes" - part no. 911.631.259.02 - and they are not very expensive. They are the same as used inside the headlamp bowl for the same purpose. Hope that helps.

I had a leak into my boot so took everything out and then poured water down the wing rain gutters. This was very educational because I could then see how the water drained to the front, ran across the seal a the front and then disappeared down drain holes and came out underneath the car. I was expecting to see water getting past the seal somewhere and dripping into the boot from the top. However what I saw was water magically coming through the boot floor at the bumper end! It transpired that over the years careless grounding of the front tub (as evidence by a few dints underneath and wonky bumper 'smile') had caused a hair line crack in the tub. The draining water was running down the outside of the tub at the front and then seeping in through the crack. The simple solution was to put some body filler inside the tub where it meets the bumper wall. My boot has been bone dry ever since [:)].
 
Quick question. Is the crank case located under the first under tray or the second starting from the back and on which side is it?

Also do most of you guys keep the engine tray off or on? As keeping it reducess running temperatures but my cars temperature seems to be fine so wondering if there would be any benefit.
 
Ray,

The crankcase is bang in the middle - the flat 6 has cylinders either side. It's the big undertray (the 1st I believe) and there is much debate over whether to keep it on or take it off.

It's purpose is much debated - some say it's for noise reeduction, some for air flow. It does seem to be accepted that the engine runs hotter with the undertray fitted but in anything but a Middle East climate it probably doesn't matter either way. Apparently the Cup cars ran without the undertray (so much for the air flow arguement).

Regards

Dave
 
Is the sump plug located facing the bottom or facing the side, if so left or right. I remember that the crankcase drainage was a circular disc on my sc.

Facing the side, left side of the car (exhaust CAT side). If you take it completely out make sure you have a big bowl. Even though there is less in there, at least 3 litres came out of mine when I tried to drain a bit because of an overfill. Some recommend you loosen it and just let the required amount drip out without completely removing the plug.
 
Well located it. 4.5 litres came out and 3 litres went back in. There was an extra 1.5 litres in there and as a result the oil pressure is better it sits at 1 bar at idle and raises to 3 under minimal load and then rises to 4/5 when under heavy load.

I am now much happier as I was still apprehensive about the pressure. Now at least I can drive car how I like rather than being too careful.

Cheers
Ray
