And many of the bigger engined Cavaliers also had weighted crankshaft pulleys.
Blimey those weighted pulleys are heavy.
It wont be done this year anyway, as far as im aware theres good life left in the clutch yet so i might as well make use of it however as she gets a few long runs under her belt it may be a different story but we'll see.
A few bits arrived today in the post:
A new genuine GM lower intake manifold flange. I believe this comes on the X25XE engine as standard. Should be a nice wee upgrade for keeping things a bit cooler rather than the one that comes on a C25XE engine.
A New ignition module/amplifier. Ive been reading through different V6 threads on forums and seen 2 or 3 cases involving this wee chap with messing about only allowing 4 cylinders or 5 to run at idle etc and you cant really tell as the V6 is smooth. The blame is then put on the ignition coil which was probably alright in the first place but is replaced first along with ignition leads...
So since i bought the cav the first place i wanted to start was refreshing what i could to try eliminate any problems that were more than likely going to develop anyway as months went on with more driving from being sat around for a good 17 years.
I replaced the ignition leads, spark plugs, fuel filter, ignition coil and the most noticeable was the new fuel pump that was put in. When i bought the car it took a good 3 to 4 attempts to get her started and idling. I just put this down to well it needs a damn good service anyway. But as i started ordering bits and pieces i thought what the hell do as much as i can then i know what i have. One of these things was a fuel pump.
So i took the old one out and immediately noticed the difference in size between the 2 pumps so i thought i had bought the wrong pump. I put the part number into google of the pump which i had taken out and could only link it with being the pump for an engine that was max 1.8 litre. Corsas, novas etc and the max pressure put out by this pump was 0.7 bar.
Done another bit of googling and found out that the standard fuel pressure for the C25XE engine was 3 bar.. what a big difference. So got my new pump in which was rated for 3 bar, so was the right one for the job and voila. She has started first turn everytime since and sounds/runs alot better.
A few months back i also sent the fuel injectors off to be ultra sonic cleaned as you can see from the picture above and according to the results they werent too bad at all from what i can see. It says the balance was brought to 0% which is good. The main thing i wanted to know is if they passed the leak test and they all did. I guess Bosch done a good job there then.
Apart from that i done another few jobs if you see the pictures in the first album i posted which included doing the oil cooler. This was quite a tricky job as its buried in between the V of the engine but just took my time and it worked out OK in the end. Had to strip back down to it again though a 2nd time as 2 of the wee washers for the banjo bolts that screw into the 2 holes for the oil cooler had fallen onto the ground when first removed.
So once i started it up for the first time i just seen the oil coming out at both ends so sadly had to undo all... but was happier when i found the washers on the ground.. these were 10 pound on eBay!! Madness. So saved a lovely tenner there. What a joke. But anyway job done... Again i know what i have now.
The oil cooler that came out seemed good. That was at 100k miles dead.
I also done the Thermostat. This is right beside the oil cooler. This was harder done than the oil cooler. The tube that connects into the housing and goes onto the curly hose onto the radiator was a nightmare to get off. It just wouldnt pull off AT ALL. Until i was finally going to give up until i wedged a 22mm spanner i think it was in between the bracket and were the bolt goes in for the dipstick and it came out eventually! So got the new one in and greased up the tube for the next time... Theres always a next time right?
Apart from that easier jobs was replacing the rubber bong for the ariel. Made a nice difference appearance wise anyways. Wind deflectors put on, which were very tight may i add. Just left them for 2 days and the windows must have bent them into shape because now the windows go up and down no problems.
Found a new old stock GM fuel pump relay on eBay. So put that in also, as from what i read these die out too with heat and general age.
Also fitted new Handbrake and gearstick leather inside. Again completed the interior inside. Freshened it all up nicely.
Fitted a new radio also. JVC.
Changed the cam cover seals as well. I didnt see any oil on the ignition leads when i took them out to be changed for the new ones which was good. But never seen a reciept for the cam covers ever being done. So for the sake of 20 quid and a tube of cam cover sealant i done them anyway. This was a really easy job in the end for me anyway. As someone had done them! There was no sealant or oil to scrape etc it was all done and all nice and shiney anyway. So happy days. So i put my new cam cover seals on and so on and thats that done also
So yeah done quite a bit i suppose... so far.
.... To be continued
Thanks for reading.
; it may well burst the dodgey broken down end with the jubilee clip likely the only thing stopping it leaking.
. If anyone has had a similar problem.
