monk3y Posted June 6, 2012 Share Posted June 6, 2012 (edited) So I got this engine for free with a transmission I just got, I got it for free because it dropped a valve killed it. I was told that the guy he had bought it from but like $3k into the engine. When I pulled it apart I noticed the crank had been drilled into. I would like to know if you could help me identify what I have here. I know it's an n42 block and n42 head (the head is toast) but beyond that I don't have a clue.

B. Whisky Posted June 6, 2012 Share Posted June 6, 2012 Everything i see looks to be oem (cant be sure on rod bolts from the shots). Assuming that bore's intact (doubtful) as well as the crank journals, you still have a useable block, minus one piston and possibly the rod.

johnc Posted June 6, 2012 Share Posted June 6, 2012 Agreed. Looks like a basic stock bottom end with 1mm oversize pistons. Nothing special and with the damage shown I would probably just toss it and find another bottom end to build from. Quote Link to comment Share on other sites More sharing options...
monk3y Posted June 6, 2012 Author Share Posted June 6, 2012 Alrighty I wasn't sure, so I figured I would ask. Thank you. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted June 6, 2012 Share Posted June 6, 2012 I got about $40 in scrap when I scraped my old block which had similar damage. So at least you get some money out of it. Quote Link to comment Share on other sites More sharing options...
pcakes55 Posted June 7, 2012 Share Posted June 7, 2012 The crank is fine, mine was exactly the same with the holes. Quote Link to comment Share on other sites More sharing options...
Lazeum Posted June 7, 2012 Share Posted June 7, 2012 The holes on the crank are normal, it is to balance it. Being in the US, I would try to find another one. Quote Link to comment Share on other sites More sharing options...
B. Whisky Posted June 7, 2012 Share Posted June 7, 2012 (edited) I would say save the rods and crank if they check out and toss the block. Never know when they'll come into play. I'm running a rebuilt f54 with rods and crank from an l26. Out of the three cranks I have, that one was by far in the best shape. And it was the one I've been sitting on the longest.

monk3y Posted June 7, 2012 Author Share Posted June 7, 2012 I am going to junk the block and obviously the head but I might hold onto the crank. Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 8, 2012 Share Posted June 8, 2012 Every week or so someone is looking for a cam with rocker arms and towers. You could sell the head for those parts alone probably. Quote Link to comment Share on other sites More sharing options...
monk3y Posted June 8, 2012 Author Share Posted June 8, 2012 Good point. On the cam I can make out E30 and SS is stamped into the front, does that mean anything? Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 8, 2012 Share Posted June 8, 2012 (edited) There should be a letter - http://atlanticz.ca/zclub/techtips/cam/index.htm Your picture and description don't quite fit with the cam for an N42 head though. I think that the N42s had the spray bar and the N47s went to the internally oiled cam. No spray bar, plus pretty sure that I see an oil hole on a lobe. Maybe there was a transition period for the cam. Probably an A cam, either way, which seems to be one of the more popular stock cams. Anyway, someone will probably need it in a couple of weeks...

monk3y Posted June 8, 2012 Author Share Posted June 8, 2012 There is just the two letters SS on it and the E30 on the side of the cam. I am just going off observation as the head says N42 along with the block. Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 8, 2012 Share Posted June 8, 2012 Aftermarket? That's all I know. Good luck with it. I fixed the link in my last post. Meant to connect to atlanticz's page. Quote Link to comment Share on other sites More sharing options...

It probably depends on what year it was manufactured. Quote Link to comment Share on other sites More sharing options...
Xnke Posted June 10, 2012 Share Posted June 10, 2012 the cam stamp will be on the back of the cam, not the front. Quote Link to comment Share on other sites More sharing options...
monk3y Posted June 13, 2012 Author Share Posted June 13, 2012 (edited) There is no markings on the back of the cam. Can anyone give me some insight on this cam? Edited June 13, 2012 by monk3y Quote Link to comment Share on other sites More sharing options...
Xnke Posted June 13, 2012 Share Posted June 13, 2012 It's probably a stock cam grind. The marking will be faint...take some fine sandpaper and lightly rub across the back of the cam, often this will show the marking very clearly. Quote Link to comment Share on other sites More sharing options...
