WOW... A revelation!
Hi all
I trust the weekend was excellent!? As far as my Volvo was concerned, it was brilliant! As was told in a previous thread, I recently transplanted a B18 into my '69 144 to replace a B20. I found the B20 a bit tired interms of rev range and was never truely happy with her. It can be said that she wasn't slow, certainly no complaints there, but I felt she could be better. I then found a '68 142, which was a steel, that had a B18 which felt a little smoother yet needed a ring and big end bearing change. Not to mention a bit of clean up. So a friend and I embarked on this little adventure and 2 weekend of work later we had a "fresh" B18 in the '69 and a tired B20 in the 142. When we started her up for the first time I felt she was a little rough but you could feel the smoothness of the wind up was better. I had an attempt at setting the clearance of the valves and did the timing by ear and sort of set the carb. Yes I know, save the scorning, but I had never experienced the potential smoothness of a B20/B18 ever. Even driving other B18's that had supposedly just been in for a scheduled tune by the "master" mechanic never felt THAT good. And so I never new any different. Subsequently, in the last few moths after the transplant, I thought I had taken a step backward. I needed to spent time tuning and I was just not getting round to it. The thing I hated most was the clattering of the valves that were hopelessly out of clearance. I cringe at the thought still. BUT the story has a happy ending... I decided this weekend that it was now time to iron out this rubbish and a friend and I took it on! We started with setting the proper valve clearance after warming her up. We started her after and the sounds was glorious! Not a tick to be heard. Magnifico! Then we checked the dwell. This lead to a bit of disaster as we stripped the hold down screw for the points and had to take the plate out and retap it. It worked for a bit but then stripped again. We eventually decided to take the distributor from the B20, which had a better one anyway (changed from a 009 dizzy to a 003 dizzy). After this minor mishap we set the dwell to be correct. Having done this we got round to the timing and this was fascinating. We marked all the timing marks with white paint and then proceeded. I am still asstounded as to the sensitivity to which the timing is set. Won't ever attempt it with an ear again. The strobo is an amazing tool! The revalation by now was incredible. Smoothness, quietness, it was all there! Lastly was the carb setting. We hooked up the vacuum gauge to the manifold and set it up. We took the car out for a test drive and it is completely transformed! I can't explain the difference! I mean when in top gear and cruising, a blip of the throtttle and the car just wants to run away. Amazing. Oh, did I mention that the car is only running a single SU-HS6 carb!? Curtisy of Mr. Agent_Strangelove I am awaiting a twin set and I can't wait to feel the difference (If bloody customs would release them I'd be greatful!). She is also SOOOO smooth! I've never felt a B18/B20 engine like it. I guess the moral of the story is to make sure that the finer details matter and being meticulous really does have its merits. I can now understand why there are guys that spend hour under the bonnets of their cars perfecting their babies! Guys, I wish the same Volvo experience upon everybody here and the to those who have yet to experience it! Dylan Last edited by Dylan144GT; Jan 12th, 2009 at 08:12. Reason: Spelling ... OOPS! :) |
