86 325e sedan build

Postby 87e30 » Sun Jul 19, 2015 1:10 am

So I finally got around to starting to work on the new project. I know it sat for at least 2 and a half years. The shop owner that I bought it through claims it ran when it was brought in, but it just needed a distributor. I know it's got several new parts. New control arms, brand new plugs (they look like they were installed and NEVER saw an engine start), plug wires seem pretty new, and other stuff I can't think of right now.

There's something about a fresh project that always makes you sparkly eyed and happy about the possibilities that the car can become.

This car has 12k more miles than my E46 wagon lol.

Started doing the timing belt/water pump/etc today. Realized I'm gonna need some more parts. Thought I'd ask to see what else everyone recommends I replace while I have everything apart. I ordered the complete timing kit from FCP Euro. I got the "better" of the 2 kits they offer for the same engine. I accidentally broke the coolant reservoir when I was removing the water pump. Forgot the hose was still attached and SNAP went the plastic. ARGH! I know I have one from a junk yard sitting at home somewhere. Anywhere to get an inexpensive NEW replacement?

The distributor doesn't look bad at all to me. I did order a new Bosch cap and rotor, but is my old one really bad enough that it would be causing problems? I know someone (yoshi maybe?) mentioned maybe CPS sensor or something. Part numbers? I'd rather replace everything that COULD be wrong now so I don't have to rip everything apart again once I put it back together.

I forgot to get new belts. I did get the only 2 radiator hoses that Pep Bitches had in stock. Was considering replacing ALL of the hoses at once. Should I go silicone? Any suggestions of where I could buy the whole set of hoses at once? I found http://www.hiperformancestore.com/BMW.htm that has silicone vacuum hose kits, but their rad hoses are 1988+.

Looks like valve cover gasket has been leaking pretty bad for a while. Got new gasket with the timing kit. Also got all the seals and whatnot that I don't even know how to replace.

Timing belt is pretty cracked all around. I'm glad I didn't listen to the person who kept insisting I crank the engine first before ripping everything apart. Looks like it'll shred any second. Looks much worse in person than in the picture.

My 89 is just barely over 100k. The LS2 has 70k miles on it. Wanna fight?

I don't care for silicone hoses. Rubber works fine. It's not a show car you know? I'm not really sure on the res. I'd just get another one from a JY but maybe pelican? That's where I go for all my replacement parts. Tischer isn't bad from what I hear. Don't really know if you can get their stuff online. It's a physical shop near a dealership near me IIRC.

The CPS is usually fine. People just mix up plugging them back in and swap it for the magnetic thingy on the plug wires. So um, don't mix those up. Of course, if the motor cranks but you get no fuel injector or spark plugs firing, the CPS is likely. IE, if you get fuel pressure but not fuel injectors firing. Course, while you're at it, a fuel pressure gauge couldn't hurt. I've had no starts from shit pumps before. Rust in the tank clogs stuff up or the pump just gets old and the seals dry out from sitting in a low tank for too long.

The distributor itself looks fine but you might as well replace it. I've seen them internally crack but physically look fine. Better safe than sorry. Especially since you already have the parts.

Only other suggestion would be to check the cam seal behind the cam cog to see if it's leaking. The VC was leaking pretty badly so I can't tell. But, if it's bad and you get it all back together, you got to take ALL that mother fucking shit BACK out to replace it. And it's like a $10 part. You know?

Keep updating. I love threads like these.

Order a set of new cam eccentrics, after 100k+miles they get worn and won't adjust correctly. Cheap and can make a noticeable difference. Cap looks fine, but if you already ordered a new one, replace it. If you valve cover was leaking that bad it would cause a vacuum leak, which may be a big part of why it wasn't running right. While you have it apart, replace that timing gear with the cast one from a late model, the stamped ones are known to deform and let the belt slip. Check the seal on the VC cap, can also be a culprit for vacuum leaks. There isn't anyone providing a complete rubber coolant hose kit, I searched when I replaced all mine. Call Blunt and he can put a kit together for you at a fair price. Same goes for the coolant reservoir, though even well priced ones aren't cheap. Unless you really care about looks the used one you have is the better option if your on a budget. New ones are around $80 IIRC.

It looks like someone removed the lifting eye on the front of the head, make sure you either put one back or find someplace to tie the upper radiator hose back to or your fan will eat through it. If you need one let me know, I may still have mine laying around, you can have it.

Not sure if it "wasn't running right", or "wasn't running at all" before. I'm really hoping it just wasn't running right.

About to put through an order right now. Getting new poly alternator bushings (the rubber ones literally melted out of the holes), NEW coolant tank (why the hell not?) AC/PS/Alt belts, new alternator adjusting bracket with bolt and adjuster nut (I have several "junk ones", but screw it), new hood shock, and earlier today I put in the order for the full set of purple silicone vacuum hoses that comes with all of the smaller diameter coolant hoses as well. Was a really tough decision between purple and blue, but purple won. I'll probably want blue when they get here lol.

Definitely gonna do the cam seal this time. Watched a video from e30source on youtube that showed me how to change it. Very good video on replacing m20 timing belt, etc. Anyone know the exact size needed for the o-ring on the back of the cam seal holder thingy? My kit did not include the o-ring, but I hear it's pretty much useless to replace the seal if you don't replace that o-ring at the same time.

What's a lifting eye?

Not gonna worry about cam eccentrics at the moment. I just need to get the car reliable enough to daily while I take the 87 iS off the road to work on. Then when I have TWO reliable vehicles I can do more projects that would cause one or the other to be down for extended periods of time. I'm trying to just get it on the road fast because the other one is starting to scare me.

I was looking into getting a cast timing gear, but most sources I found say you need an adapter to put the newer gear on the older engine. Have not been able to find any other info about such adapter though.

What about the crank pulley? I've read stories of them actually coming apart, but when I looked at mine I don't see how that's possible.

I know I'm gonna need more parts. Hopefully I can get everything I actually NEED before Saturday so I can try to get it started.

The alternator has bushings?

lifting eye is the little handle that attaches to two points on the valve cover/head area so you can lift it with an engine hoist. It technically goes behind the timing cover and bolts in the top two bolt spots. It's also a spacer so you might REALLY want to put it back.

I wouldn't worry about the timing gear. You aren't futzing with it so the factory one is more than fine. As long as it isn't the first gen style stamped one. IIRC those break?

I've never seen a crank pulley break. I think you're fine with that. Not like the motor grenades if it breaks either.

I'm in a similar spot myself. "well, I'm here. I might as well replace aFASDHGA Eafhnoispvuha,nfeafheslifjaei avnsaf and the seat cushions"

I didn't know it either, but I noticed very mushy melted looking rubber sticking out when I was trying to move the alternator to take off the belt and when I looked it up I saw replacement bushings so I ordered them.

Oh I removed that when I took off the timing cover. I'll be sure to put it back.

I have a set of tan "comfort" seats that I'll most likely never use. Why do they call them comfort when they're not comfortable?

The cam eccentrics go on the end of the rockers and literally take about 10 seconds each to replace, and cost maybe $0.80 each? I'd replace them.

You can remove the lifting eye if you use spacers to move the timing cover out, thats what I did, but yes you need either one or the other or you will have issues.

He has the stamped sheet metal timing gear Yosh, look at the pics.
