  1. Don’t even know what to call the part , but it’s cracked and don’t know how important it is . Can I used an earlier metal bushing ?
  2. Good advice Captain . The finger tight caps can be an issue
  3. Question : did this cam turn freely in this head before ? Did you mark them before removal in order to get them back in proper placement? Have you checked the head for flatness ?
  4. I wouldn’t be concerned about the second ring being a little oversized . Conventional thinking has changed about the gap size on the second rings over the years . Now the engineers like to see a larger second ring gap to make sure pressure doesn’t build between the two rings and cause ring flutter . I didn’t have as good of luck with my oversized rings . The box oddly said STD- .010 . The gaps still came in too big . Sounds like you have a winner !
  5. I have also heard of his technique of using .010 over rings . I believe machinist told me that the one size over would still be concentric enough to do that . It takes quite a large gap before it starts affecting CR . I thought there was two specs . One was the range for the gap and the other spec was replacement range - like .039 or something . I ran large gaps on my last L28 build . All the rings were at the far range , but I ran it . Id say - send it
  6. Straight vinegar . The pump helped by keeping things stirred .
  7. Distilled white vinegar and a parts washer pump
  8. maxima vinegar soup
  9. So was there Nissan sedans in Germany ? Are they in JY’s there ? Is or was there a variant of the Maxima for that era ? That would be the head to get
  10. Do you or did you have the Nissan Maxima over there ? The early 80’s Maxima used a 2.4 L6 . That would be the ideal head for your situation
  11. I’m Another HF jack off. I have two Pittsburg aluminum jacks . I’m like Cliff, I just bought the 1.5 . It’s super light and fits anywhere. I also have the 2.5 which is also great . Even with my lowered car and a front spoiler , I can fit either one between the front tire and my spoiler and reach the center of the crossmember . Jack stands save lives , not the jack
  12. Put your name on the list I guess. I’m not sure how much I will want for these . They will be cleaned , pressure tested , probably a skim cut to make sure all is flat and perfect . I might just have 44mm valves put in them all if they give me a break on quantity! I will be using at least one of them. So far they are all looking pretty good . Looking for the right machine shop to put the correct finish on the mating surface . They didn’t even offer a price with them pulling it ? I took a big gamble , but I might have got lucky .
  13. It cost more to ship . I took a gamble and bought at core prices . First two seem good , haven’t got thru the rest yet
  14. Paid for them Christmas Eve !
  15. Been calling around looking for another Maxima 47 head for a project I’m doing for a customer . I called a a junk yard that showed one available . I asked the guy if he really had one . He said “ I have 6” . I about dropped my phone . I said , “ I’ll take 4 ! “ I also picked up a 4 speed auto from the Maxima . Might as well fill the pallet !
