    Bent valve?

    I have the chiltons and haynes aswell as a how to rebuild your datsun engine. It was allegedly rebuilt but I think it was done poorly since it leaked so much oil when I bought it and had a broken valve cover bolt aswell as the back 2 bolts of the head were loose. I’ve been trying to do everything right with a lot of help from this forum and a local mechanic. I’ll post a picture of the sprocket and the I now know tensioner.

    I think it skipped a tooth because it wouldn’t idle at all and it might be the tensioner I don’t really know. That makes more sense now so I have to put the head back on and the sprocket to do it? Well I didnt think about the timing till I was like huh maybe it skipped a tooth or two or more. It idled at like what sounded like two grand to twenty five hundred but it just was just awful. It just started randomly it accelerated with some hesitation. Also it made clanking noise when it high idled like that. I thought it might be the valve slapping the cylinder or something in the timing chain area broke. I would like to think maybe it was just it skipping a tooth. I don’t plan on selling it either I have time invested into it and effort for me to wanna sell it maybe when it blows a rod through the block but otherwise no.

    So I know now that it’s just the timing chain skipped a tooth but it’s nice to know that headgasket has been redone. I’ve seen oil pan leaks and how to prevent them with some oil RTV by some I mean a moderate to large amount. I also do want to find where my timing chain parts went because the rail has a piece missing I think and there’s a little rubber thingy just floating around in the timing chain housing atleast it looks like rubber I couldn’t take it out. The garage mechanic does sound like a great option but I don’t want to pay that money and it’s my senior project as a requirement to graduate. I live in the sticks of the valley in Oregon so there not uncommon just pricey. I also like doing all the work myself it’s fun 9 times out of 10 but sometimes it’s a pain in the ass. How would I break the pulley bolt loose would I have to put the head back on? Because In the video correct me if I’m wrong I was half asleep but it looked like it was still on.

    Okay so I have to loosen the oil pan to get the timing chain cover off? Man datsun breaking my wallet with gaskets and shit. Yes I’m going to replace the oil pan gasket since I’m there and just do a full service since it’ll be cold soon. I watched hainz video and I know now I have to remove the oil pump drive bolts and such. I cleaned my intake up today and made a block plate for my EGR shit that’s gone.

    I got it looked at they said the valves are fine I guess TDC is just the valve is I thought was pretty far down. I pump gas part time after school making minimum wage 15 hours a week so not much. I can’t quite figure out how to get the front cover off do I have to unbolt two bolts down and left to the water pump?

    Okay, I will post a picture of the valves because the intake valve for cylinder 1 looks a little messed up so either I am going to pull it completely apart and clean it or full send with something to get the carbon and shit off, So the timing chain kit is actually $129 which is my entire paycheck. side note you do not have to remove the exhaust and intake manifolds just unbolt the flange with a little knuckle thing and just wiggle the shit out of it till the exhaust pipe falls out also it is heavy but maybe it's just because I am a small person. Also to get the timing sprocket off there is a notch in the cam for a crescent wrench to tighten onto and then just make sure it is tight and break the bolt loose and take off the timing sprocket for those who look at this in the future. Hopefully Ill have the scrapson put together by next week when I get my paycheck.

    Well looks like I’m pulling everything off top and bottom since I’m there I didn’t watch that video but during work I will

    So the guy I bought it from said it was “rebuilt” but something tells me he wasn’t being honest. I also don’t know how much it would make a difference considering all the backfiring and misfires before I got it to run at all to get it home which side note was sketch as all get out. I opened the links so anyone can see it I thought they were. I don’t have time to run a compression test because I got work till 8 and little sister goes to bed at 8 I think it’s not necessary to pull the head but I do want too just know how it looks inside and replace it because the shotty work on it. Also timing chain, tensioner and rails are like $60 I mine aswell pull the top end off and the front since I am there.

    Okay so what happens for me to say there is no tensioner is because when I pulled off the valve cover I noticed there should be a tensioner but nada.

    Chain https://drive.google.com/file/d/1iHj_V7QJ7jBMY3heVJ4vdXTwzI_xvwcl/view?usp=drivesdk plugs https://drive.google.com/file/d/1Cz4Yspix4mWRWCaB9QxhnOKzW4AujUnI/view?usp=drivesdk chain https://drive.google.com/file/d/1CWcwEPC2d-ABkTYFAoIUfllOyAZxLHEi/view?usp=drivesdk There are marks on the head from the chain slapping onto it which explains the rattle noise I could never find which occasionally happened. I’m going to watch that video I got Cheetos but I don’t think I’m getting naked and watching it.

    Bent valve?

    Yes I took it off the cam sprocket. I’ll post photos here in a second of the plugs and where the tensioner is missing.

    Side note I did wanna pull it apart at some point so either now or later but I do wanna do an overbore and small block flat top pistons and get a little more power I don’t know if that’s familiar with you guys or not but a local mechanic brought it up
  15. Scrapson

    Bent valve?

    I can get naked and watch that tonight when I get off work. I will post pictures of the plugs as soon as I get home and I’ll put the timing chain and stuff back on to do a compression test.
