    I’m not an experienced welder but I must say, the way in which you grind out all the voids is the same technique as when welding high pressure pipe. Your attention to detail is inspiringly impressive.

    In many of you haven’t noticed, one of the preparations was to die grind with the carbide burr all of the broken surface down to ‘new metal’. Even after tig welding the top, he opened up the gasket surface to ‘new metal’.
    All in all, a very nice job.

    I used to run a mobile welding shop in the carribbean for 11 years. Had a call one day to water island. Had to take a people ferry over and walk tue equipment to the job. The lady had a cracked engine block on a little suv. The bolt bosses were ripped off. I didn't have a portable AC tig just DC tig. I offered aluminum welding rods but refused to back the work. I promised to do my best but assured her it probably wouldn't work. I ordered in a huge box of rods and welded the block up. The ground with a 4inch grinder and made it mostly flat on the 3 pads. Drilled amd tapped, but only with 5/16 grade 8 bolts as per the client. That car lasted another 6 years without issues. I still don't know how it held. She paid me well and fed me. Said it was cheaper than a replacement by far. Happy customer happy life..

    Really good fix, done professionally and carefully, it will probably work great in this case.
    I know from experience that there can be major factory imperfections in these castings as well as the inlet ports to the cylinders - big bits of steel just sticking up and messing up the airflow. But you can't really fix it without removing the cylinder head at a minimum, even the smallest chip is likely to stay in the cylinder and wear away at the engine.

    There are some magicians out there. I weld like shit to be perfectly honest. In the 90s I had my local welder (back when you had a local welder!) repair a broken chrome trim piece for the nose of my '70 Buick's hood. He mostly did industrial and fleet heavy duty welding. He just had the trim I didn't leave the car. He brazed it. When I got it back in a few days, the repair was almost visually perfect and the damn thing did fit perfectly. He polished it so the repair looked much like chrome. I used it as-is for a couple of years while I found an undamaged one which were hen's teeth back then, I can't imagine it now. That guy might even be dead now, he retired in the early 2000s. An artist. I suppose he found my job challenging and interesting as a nice change of pace so he really went above and beyond. Cost? 50 bucks. Of course, me and 50 bucks were not well acquainted back then LOL.

    • @Smffab
      @Smffab  2 місяці тому +1

      Thanks. It wasn’t dropped or damaged like that. They can break when they are installed with a thermal gasket and not a OEM gasket. The thermal gasket is used to try reduce heat transfer from cylinder head to manifold and therefore have cooler intake temps, but the thermal gaskets have a lot more “give” in them as they are thicker than OEM. This means manifold flanges aren’t properly supported or if not all torqued up correctly can lead to flanges cracking and breaking. You see it on these manifold and more commonly the aftermarket intakes.

    Great video, I wish it had some voice over like what you think a good pre-heat temp should be or what kind of filler rods work best in your opinion. Belt sanding the mating surface flat works with something like this because there is no real pressure and small warping of a few thousands does not really matter. I wouldn’t attempt that without a proper face mill on a block or head though, the ruler won’t show the very slight defects that just cause leaks almost immediately.

    • @Smffab

      Thanks for the feedback, I appreciate the comments and thanks for watching. The belt sander is never going to be as good as something being machines but I checking my belt sander table it flat and I also check the part is flat with a square. The surface I get it actually really quite good, and once the gasket is on and everything tightened down to the correct torque, I don’t have any leaks and it’s running about 12-14 PSI boost pressure with no problems

    Perfect Job and nice work but wouldn't the labor to do that work be more than the cost of a new manifold?

    • @Smffab
      @Smffab  11 днів тому

      Probably half price. New manifolds are £400+, used they are £330 ish. I got this one for £150 and use it on my own car but I would have probably charged around £150 for this repair if I was doing it for someone else.

    Apparently, some of the aluminium van engines (eg vw and others), their heads can develop cracks around the injectors esp if they are not common rail injection systems (so each injector generates its pressure and creates a hammering action where they are seated on the head creating metal hardening / cracking). I've seen someone add shims around them . Are those kind of cracks something that can be welded ? I've always heard that aluminium welding is much tougher to do (from the cycle frame world).
    Cheers and thanks for the video, very impressive.

    Heating the whole piece in an oven is preferable rather just heating the localised area. Also avoid using a sanding belt linisher to re flatten a skimmed face if possible as they tend to shave a lot more off each end than in the centre and you may end up with a poorly sealing face. (Best re-skim if you can afford it).

      @Smffab  4 місяці тому +1

      Thanks. I got this part cheap so saved myself a couple hundred. I just used a butane torch just to get a little bit of warmth in it and remove moisture before I start welding. My welder is only 160amps so it helped with initial welds.

      @@Smffab Great I am tempted to try it. I want to repair the aliminium on my motorcycle engine but I have an arc welder so I need a TIG welder and argon gas so I would be better to get someone to do the repair for me. I know aluminium loses heat far faster than other metals and the window to fuse the parent metal and filler metal is narrow.

      It wasn’t really absolutely necessary, but because I have lower powered machine (max 160amps) it helped me get going with the initial weld, rather than waiting for the welder to do all the heating up before starting to add filler
