Well it seems my sweet running 420SEL was short lived a few weeks back he started to hesitate on take off. Nothing drastic but being ecentricaly in love with my car, I knew he was not feeling well. So I pulled the plugs only to find they were sooty, cleaned refitted and no improvement. So I took it out for a 200km spin and cleared out the cob webs, for one week all was good alas it didn't last.
Weird thing was, it started first turn of the key idled ok but touch that pedal and it would almost die and once warm the idle was woeful!!!! Given it's not far off 400,000km I figured thos injectors might need to go, wow there was almost no seal left on half of them and they were looking bloody tired. So having found a parts supplier in the US that is 80% cheaper then here, you know what I did. New injectors, seals and mounts, inlcuding upgraded rubber seals for mounts. Brought new pumps, filter as well as they were on sale.
Now of course all was going well till I discovered at some point the injectors had been removed and refitted and the bolt head stripped!!! Ever tried getting stripped bolts out of a 22 year old intake manifold not bloody good people!!!!
Of course as you do, you find a mirade of other old worn out bits that have helped your engine run like a dog. So I took the plunge and replaced all the rubber vacum hoses as you can see several were completely broken and I really wonder how it run at all, looking back at it.
Then I decided to replace the EHA valve on the fuel distributor as well, because it did seem to be running lean at random lucky that was on sale not cheap!
Once I finally got it all back together big job, I turned the key holy crap what have I done, it choked spluttered and died on the spot God the misses will never let me live it down if I can't get it running. Hot tip when working on a car at 2am always check things the next day, turned out I hadn't tightened the hoses to the fuel pumps, nice pool of fuel back there. So final check done turned the key and presto he runs not smooth but running none the less. So after two hours of adjusting the fuel distributor and EHA valve I finally havee him running sweet it pulls like never before and you can balance a coin on the engine it's that smooth! The power is awesome the gear chanegs heaps smoother and even the climate control seems to be working better, it's amazing what eliminating vaccum leaks can do! If you have an old car it might be time to cheack those rubber hoses and replace them whilst you can still get them!
