cockerstar Posted October 17, 2008 Share Posted October 17, 2008 Hey guys, I'm getting ready to put my rebuilt l24 with an e31 back into my 240 and I noticed a repair done by the PO, who did the engine rebuild. It looks like he tried to do some soldering, but it didn't turn out so well. How would you guys address this? I've attached a few pics for refrence Thanks in advance!

100dollarZ Posted October 17, 2008 Share Posted October 17, 2008 yeah that looks like a botch repair job. I havent worked with Z's with squirter bars, so I dont know what material is used in the pieces. If its iron/steel, it can be brazed, but Im not sure about steel/aluminum... Experience metallurgists should chime in, but I would get that repaired. Quote Link to comment Share on other sites More sharing options...
Careless Posted October 17, 2008 Share Posted October 17, 2008 I would have it replaced since you're there, but it seems as though it held up this long. Heck I bet JB Weld would hold up too as it's not an insane amount of pressure... but If you're building it up, I would go ahead and change it Quote Link to comment Share on other sites More sharing options...
cockerstar Posted October 17, 2008 Author Share Posted October 17, 2008 I'll pull the valve cover off of one of my parts cars and see if I have a replacement in good condition. My initial thoughts were to JB Weld it so I'll be going down that route of I don't already have a good one. What kind of pressure do you think it will be seeing? My build is going to be very mild - l24, flattops, header, 4-puck clutch, 4 screw round-tops with the possibility of going with webbers down the line. I'm going to be needing anything too heavy duty.

100dollarZ Posted October 17, 2008 Share Posted October 17, 2008 It sees the oil pressure of the engine, probably not anything more than 70 PSI. Quote Link to comment Share on other sites More sharing options...
zguy36 Posted October 17, 2008 Share Posted October 17, 2008 Try brazing it, solder joints are just too brittle for something like that. If you F it up in the process, nothing is lost as it is already F'd up. If that is the end result, put on a new one! Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted October 20, 2008 Share Posted October 20, 2008 We had that piece fall of in our IT car... It jammed itself between the valve and the rocker arm and caused all sorts of problems... Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 20, 2008 Share Posted October 20, 2008 That piece is a 'buy it new and don't think about it again' The time it will take you to clean and repair it properly will exceed the cost of a new one! They're under $100. Probably closer to $50. Last one I bought was $45, so figuring it went up in the last year or so... Quote Link to comment Share on other sites More sharing options...
