otay I'll post up the 7 again;











----------

picking it up in about 2 weeks. PO says the engine doesn't run, but doesn't know exactly what's wrong with it. Might be a cheap fix, whole engine might need a rebuild. No clue as it's a rotary with 171k miles.

It really depends on the make and model of the older vehicle. Some people think that they are untouchable in something that is older and heavier, but that is not always true. The general mentality of older car crash safety was to build them to withstand impact (without the technology that is used today) whereas now you have cars that can absorb and withstand them and protect you with airbags.

That doesn't mean all older cars are unsafe, but you are typically safer in a newer vehicle that has the advantage of airbags.

1967 Buick Wildcat--estimated impact was between 75-100mph





The driver lived and is fine today but was in the hospital for 4 days. If shoulder belts had been the norm back then he would have been a lot better off. Only noticeable interior damage is the steering column.

Three people in the 94 Dodge Intrepid (a car with 4 star ratings) were killed.

That RX7 is adorable Cartman372, really!
I hope you will be able to fix it, it would be a shame to let a nice car like that rot.

Well I don't know if I'd call it adorable lol, but thanks

Oh I'll definitely be able to get it fixed. If the engine ends up being beyond repair, I'll head down to a place here in NJ called JPR Imports and have them work on it.

Rotaries are easy to rebuild unless something is hideously broken, you would save a bucketload of cash if you did it yourself!

I'm not gonna lie...I know essentially nothing about rotaries. I mean I know how they work, but I know nothing about how to build/rebuild one.

Good learning experience though.

And you're right, I would save a bucketload of cash.

The plans are if the engine needs a slight fix, fix it and run it as is. If the engine needs a whole rebuild. I'm shooting for turbocharged and around 300-350hp.

EDIT: Also picking up a Turbo II hood ,Turbo II intercooler and a set of Turbo II wheels. It'd be nice to be able to use the TII Intercooler when/if I go over to turbo power, but we'll see what happens.


Hood;




Intercooler;



Wheels;

If you want to follow the build thread of my 7, you can head over to my forum at

Since there's no appropriate place to put a build thread on this forum.

Hmm... my Accord is still using way too much oil, so it couldn't have been the valve seals.

Is it possible that it's leaking oil through the head gasket from an oil channel into a cylinder? I already have a new head gasket lying around but I'm not taking on that job myself. I will get a compression test done this week, but I'm guessing that won't tell me if it's the head gasket or the piston rings?

Have you pulled the plugs? If it's the head gasket it would usually only show on one or two adjacent cylinders. Maybe your PCV is blocked?

Yeah I started thinking about the PCV valve myself. A blocked valve will create excess pressure, right? Because I just got oil leaking into the spark plug holes and from the valve cover seal. The valve cover itself looked nasty when took it off. I've changed all the seals and o-rings and that seems ok now, but still... The PCV valve is positioned on top of the valve cover in this engine.

I'm gonna get that checked out tonight.

Well unfortunately it gets a little complex. You can do the compression check. Look for two adjacent cylinders with low compression. The general rule of thumb for GM and Ford is that the cylinder with the weakest compression should be no less than 75% of the maximum cylinder. I would assume that Honda would require the same. Two adjacent cylinders would leave me to believe that it is most likely a head gasket...but it may not be.

A wet compression test can help to find ring problems. You will pour a small amount of oil into the spark plug hole and then check compression again.

Guys will argue about the validity of a wet compression test, whether testing should be done hot or cold, the pistons must be level, etc. Those who say it does not will want you to do a leakdown test in which you would need an air compressor and a tester. This is the method that a garage would do, the former being more of a poor-man's way of doing things. I would try it and look for any dramatic increases. I can't give you a number to look for on how much % increase you would have due to worn rings because I simply do not know. Even on a fresh engine build, you will get a higher reading with a "wet" test because that is part of what the oil is doing in the cylinder to begin with.

Without doing a leakdown test and having the gauge for that, you can manually turn the crank until the piston you are testing reaches TDC. The valves should be closed at this point. Spraying the compressed air into the spark plug hole can show valve leaks as you would have air coming out of your intake, carburetor, etc.

Is this an overhead cam engine?

Yes, it's a SOHC engine.

About compressed air though. I changed the valve seals without taking the head off by connecting an air compressor to the plug holes to keep the valves up. While you could clearly hear some air leaking (on all cylinders), we attributed that to general wear and tear. I don't think you can expect an old engine to be air tight around the pistons with the amount of air pressure we used.

The compression test will be done by a friend who's a mechanic by profession. I'm sure he knows what he's doing, haha.

Yup. All bolted in correctly. Just gotta install some stuff onto the engine, figure out the wiring, and some body work.

Messing around in Photoshop.
Trying to make the 2012 Impreza not look so boring and thankfully it looks like it won't take much to change to make it look more sporty. I'm pretty much set on this car now. I was really set on the 2011 WRX and didn't think MPG would be such a selling point a while back, but it sure is now.
It's not the best looking car, it's not the fastest, but hell, I'll take it for what it offers, which is AWD and a welcomed 27/36 MPG. Compared to my last POS that was 20MPG, it really starts to look good despite it's physical appearence.
I do plan to try and get it up to about 200HP, add some wider/lighter rims, better suspension that can withstand offroad driving, and some chassis stiffening. The car is lighter than the previous years, but I want to try and reduce it further.
Makes it seem like I should just buy a 2011 WRX, but I kinda think they are overpriced a bit. 2012 Impreza is going for about $18K, and 2011 WRX is still around $30K here...So I was like **** it, 2012 Impreza it is! It also uses regular gas, woot!
I'll probably get it the month it comes out, so now I just have to wait a few months...
