banzai510(hainz) Posted June 26, 2020 Report Share Posted June 26, 2020 if the exhaust smell is bad maybe the gasket on the manifold where it meets the exhaust pipe is leaky getting in the cab Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 Block vent may be off or no hose connecting it to the PCV valve. Oil sprays all over the hot exhaust causing smoke and high oil consumption. Should have this pipe coming out of block behind the exhaust manifold with a bend, then a hose going to the intake at base of carburetor. If PO left the engine plate off they may have left the screen off inside and fucked this up also) Below is the hose (silver) to PCV valve 2 Quote Link to comment
KDW_80-720 Posted June 26, 2020 Author Report Share Posted June 26, 2020 Is that cut off tube there what you're talking about? Or the two open tubes parallel ish? I can't quite get that shielding off yet, there's a rusted ass stripped bolt holding it on. I will say that if it's supposed to be those parallel tubes that there is splatters of oil that go through that., not a lot at all. Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 The pipe at the front is from the missing air pump and directs air into the exhaust ports to reduce emissions. The block vent comes out of the block and you can see it beside the hand brake cable and just under the throttle cable. It should have a hose on the end connecting it to that block off plate under the carburetor. That block off plate should have a PCV valve screwed into it. Because it is soo clean it's not the block vent pipe causing the oil loss or smoke but you really should get the PCV valve working. Quote Link to comment

Great, I will be getting that taken care of as well... odds are it's probably the piston rings and maybe seals then? The oil was pretty thin and gassy. This has the weber on it, which I know nothing about. My Z24 had the stock carb which I could figure out relatively easily. I'm assuming there is adjustments on it somewhere, is there a link on this site or somewhere I can find that information? I appreciate the input Datzen and everyone else. Quote Link to comment
banzai510(hainz) Posted June 26, 2020 Report Share Posted June 26, 2020 well that metal line on back side of the exhaust manifold unless its plugged that's whats killing you with exhaust smell Doh!!!!!!!! Quote Link to comment

I'll get that all off when I'm there. I hope it's just threaded into there so I can put a plug in it.. Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 Exhaust leak? could be the smaller curly pipe on the exhaust manifold. I assumed who ever did the EGR delete would have sealed it. Maybe not. That block off plate has hole.... is it plugged?? Previous owners are idiots. All this for an EGR delete and just fuck it all up. And for what??? so it looks cleaner/neater??? No wonder there's missing engine plate. Quote Link to comment

wayno Posted June 26, 2020 Report Share Posted June 26, 2020 (edited) I see the hole where the PCV was likely supposed to go, it looks like it is open to the air, if it is an open hole your going to need to fix it, it will not run properly with an open hole like that. Your a half hour north of me, I live in Vancouver WA, if you need help let me know. Edited June 26, 2020 by wayno 2 Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 He's driven it. Must have a plug in it. Quote Link to comment
KDW_80-720 Posted June 26, 2020 Author Report Share Posted June 26, 2020 Okay, so theres supposed to be a tee coming out into a new hose out of that block off plate? I don't have any diagrams of the OG set up. Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 A tee would face the PCV towards the block vent hose at least. Quote Link to comment
KDW_80-720 Posted June 26, 2020 Author Report Share Posted June 26, 2020 I work at a hose/fitting supply shop...should both of those tubes be connected by hose with the PCV in the middle there? There was a hose on the pair of those tubes that I removed? Quote Link to comment
datzenmike Posted June 26, 2020 Report Share Posted June 26, 2020 Sorry I meant to say 900 bend facing the block vent. Like this... In addition the front metal pipe facing the rear below, should be sealed... it connects to the exhaust manifold and will leak exhaust. 1 Quote Link to comment

Hopefully once I get my FSM I'll actually have some sort of information that I can get through most of. but I will definitely keep it in mind, I am sure I will need help at some point Quote Link to comment
KDW_80-720 Posted June 26, 2020 Author Report Share Posted June 26, 2020 Okay, so that first tube doesn't need to be hooked up to the PCV? I'm sorry for asking same shit over and over, but I want to make sure that I'm getting this understanding correct. The only that needs to be hooked to PCV is going to be the one from the block vent and that other tube is exhaust related? was connected to something else that is no longer there? lol there was a hose he had connected to both of those tubes that are open, im guessing bypassing the PCV.

wayno Posted June 26, 2020 Report Share Posted June 26, 2020 The thing is a FSM is likely only going to show you how it is supposed to be, but yours is modified so you need to put the PCV in that hole in the plate and put a hose on the tube near the e-brake cable to the PCV valve, you then need to plug all them other tubes hanging out everywhere. 1 Quote Link to comment

Perfect. I'll find something to seal those off. Quote Link to comment
KDW_80-720 Posted June 27, 2020 Author Report Share Posted June 27, 2020 https://imgur.com/gallery/uLG0sGD is this the plate you are talking about? I don’t see any spot for a PCV if this is what you’re talking about Quote Link to comment
datzenmike Posted June 27, 2020 Report Share Posted June 27, 2020 Looks like the holes don't line up. The PCV would normally go in the top center hole. EGR gasses into the holes on either side. Here's mine which was similar. I filled one EGR hole with JB weld and tapped the other to take the PCV valve. The middle hole I tapped for a vacuum supply. The rest I ground away so it would look like an earlier non EGR intake. For you it would be easier to drill and tap that cover plate and fit a PCV valve. Quote Link to comment
KDW_80-720 Posted June 27, 2020 Author Report Share Posted June 27, 2020 The plate does have a hole tapped in it. And a gasket behind that Quote Link to comment
datzenmike Posted June 27, 2020 Report Share Posted June 27, 2020 I don't think they look like the line up, do they??? Getting the PCV working isn't a high priority but it need to be done. Quote Link to comment
KDW_80-720 Posted June 27, 2020 Author Report Share Posted June 27, 2020 Oh no, the only holes that lined up are mounting for the plate. Anyway just trying to get this out. transmission drop then engine pull or all at once? Quote Link to comment
datzenmike Posted June 27, 2020 Report Share Posted June 27, 2020 Ginger or Mary Anne? I would pull them together. Easier to get at. Drain transmission and remove rad. Maybe pull distributor cap and wire off so they don't get smashed. 1 Quote Link to comment
