Hey everyone

have a quick question does anyone have a photo of under there engine on a r33 coupe? I’ve tried googling but got not nothing

 

reason for this, is my engine builder finally has the new engine running in the car and is telling me the sump is now leaking oil around the welds. He needs to remove the sump to fix it, But he needs to take the engine back out of the car, for when he goes to reinstall, he wants to make sure it fits 100 percent. He says a cross member and other stuff is in the way. Surely this couldn’t be right? 
 

couldn’t imagine you would have to take a motor out of a car just to put a sump back on?

Yeh generally its much faster and easier to take the engine out. Ive seen it done with the engine in by unbolting the engine mounts and lifting the engine enough to get enough room in, but its bush mechanics 101 and not something a professional mechanic should be putting his limbs at risk with.

 

Shouldn't be that bad though, engine out is a 2 hour job, 3 hours max.

Thanks very much everyone for the info

wow I’m surprised by the answers I got.  Well ya Learn something every day I guess

 

I get why you asked the question though, plenty of cars don't need to pull the motor out to remove the sump. We are just lucky I guess lol.

You can do it in the car, I've done it. Strap motor up, undo LCA, remove subframe, undo engine mounts.20190210_141441.thumb.jpg.80893184f2bab434e758ccae92e1aa71.jpg

But.. you're better off taking the motor out.

 

You could eat off that!

I've never done it but seem to agree with hardsteppa.

Removing lca's and cross member 

VS

complete engine and associated bits

I reckon I'd go option A.

Option B sounds excessive but as i said I've never done and not talking from experience.

This feels a bit like do you prefer blondes or brunettes....

I'd take the engine out for sure rather than drop the x member (noting dropping the x member is a hoist only option in practice. Apart from anything else, it lets you have easy access to properly clean the bottom end for resealing the sump.

Trying to remove the sump bolts with the motor on, then trying to remove the sump itself is very challenging (even with a hoist).

If you were doing this on jack stands, it would add even more complexities. And no, you can't use car ramps as with the subframe out there's nothing support the castor rods/LCAs.

Motor out is better.

I did manage to do this without removing the engine or front cross member, but I had the advantage that the exhaust manifold was removed. I am not setup to support the engine from the top or remove it.

1. Loosen the engine mount nuts so they only have a nut of thread. If it is a manual, I think you have to remove the gearbox to engine support brackets.

2. Jack up the engine off the bottom idler mount. Jack it up till the end of the slot and nut on the mount. You need this clearance to get the pan out at the rear of the engine.

3.Break the sealant seal to sump. I found a oil pan separator tool helpful to get it started.

4. The oil pick up can be removed with the gap available. 

5. The oil pan can be removed now.

6. Before assembling, do not apply sealant to the oil pick up area as your hand will rub it all off but apply to the other three and a bit sides.

7. It is a two man job to put the oil pan back, with the sealant, as you do not want it to touch anything and rub off.

8. With one person supporting the oil pan the other can fit the oil pickup

9. Apply the remaining sealant. This would be more difficult with the manifold or turbo in place, but I think it could be done. As you can see my sealant is a bit ugly, but good enough to seal.

10. Lift the sump up to the engine and bolt it on. We found it was easier to use two long guide bolts at each end to get it nice and aligned without touching.

I think I'd settle for just pulling the engine. Then may as well have everything else inspected while you're at it and think about throwing a stroker kit in there with valve relief pistons for 50 degree advance VCAM and maybe a spline drive oil pump and other oil control mods on top of that and maybe a helical front LSD too.

    • This is for an RB20DET. Sorry for not including that. 
    • Welp, this is where my compression lands after my rebuild. Thoughts? I have ~6 hours on the motor. 
    • Well, after the full circus this week (new gearbag, 14 psi actuator on, injectors and AFM upgraded, and.....turbo repair) the diagnosis on the wastegate is in. It was broken. It was broken in a really strange way. The weld that holds the lever arm onto the wastegate flapper shaft broke. Broke completely, but broke in such a way that it could go back together in the "correct" position, or it could rearrange itself somewhere else along the fracture plane and sit with the flapper not parallel to the lever. So, who knows how and when exactly what happened? No-one will ever know. Was it broken like this the first time it spat the circlip and wedged itself deep into the dump? Or was it only broken when I tried to pry it back into place? (I didn't try that hard, but who knows?). Or did it break first? Or did it break between the first and second event of wierdness? Meh. It doesn't matter now. It is welded back together. And it is now held closed by a 14 psi actuator, so...the car has been tuned with the supporting mods (and the order of operations there is that the supporting mods and dyno needed to be able to be done first before adding boost, because it was pinging on <<14 psi with the new turbo with only a 6 psi actuator). And then tuned up a bit, and with the boost controller turned off throughout that process. So it was only running WG pressure and so only hit about 15-16 psi. The turbo is still ever so slightly lazier than might be preferred - like it is still a bit on the big side for the engine. I haven't tested it on the road properly in any way - just driven it around in traffic for a half hour or so. But it is like chalk and cheese compared to what it was. Between dyno numbers and driving feedback: It makes 100 kW at 3k rpm, which is OK, could be better. That's stock 2JZ territory, or RB20 with G series 550. It actually starts building boost from 2k, which is certainly better than it did recently (with all the WG flapper bullshit). Although it's hard to remember what it was like prior to all that - it certainly seems much, much better. And that makes sense, given the WG was probably starting to blow open at anything above about 3 psi anyway (with the 6 psi actuator). It doesn't really get to "full boost" (say 16 psi) until >>4k rpm. I am hopeful that this is a feature of the lack of boost controller keeping boost pressure off the actuator, because it was turned off for the dyno and off for the drives afterward. There's more to be found here, I'm sure. It made 230 rwkW at not a lot more than 6k and held it to over 7k, so there seems to be plenty of potential to get it up to 250-260rwkW with 18 psi or so, which would be a decent effort, considering the stock sized turbo inlet pipework and AFM, and the return flow cooler. According to Tao, those things should definitely put a bit of a limit on it by that sort of number. I must stress that I have not opened the throttle 100% on the road yet - well, at least not 100% and allowed it to wind all the way up. It'll have to wait until some reasonable opportunity. I'm quite looking forward to that - it feels massively better than it has in a loooong time. It's back to its old self, plus about 20% extra powers over the best it ever did before. I'm going to get the boost controller set up to maximise spool and settle at no more than ~17 psi (for now) and then go back on the dyno to see what we can squeeze out of it. There is other interesting news too. I put together a replacement tube to fit the R35 AFM in the stock location. This is the first time the tuner has worked with one, because anyone else he has tuned for has gone from Z32 territory to aftermarket ECU. No-one has ever wanted to stay Nistuned and do what I've done. Anyway, his feedback is that the R35 AFM is super super super responsive. Tiny little changes in throttle position or load turn up immediately as a cell change on the maps. Way, way more responsive than any of the old skool AFMs. Makes it quite diffifult to tune as you have to stay right on top of that so you don't wander off the cell you wanted to tune. But it certainly seems to help with real world throttle response. That's hard to separate from all the other things that changed, but the "pedal feel" is certainly crisp.
    • I'm a bit confused by this post, so I'll address the bit I understand lol.  Use an air compressor and blow away the guide coat sanding residue. All the better if you have a moisture trap for your compressor. You'd want to do this a few times as you sand the area, you wouldn't for example sand the entire area till you think its perfect and then 'confirm' that is it by blowing away the guide coat residue.  Sand the area, blow away the guide coat residue, inspect the panel, back to sanding... rinse and repeat.
