What can I do? I've lost 2 motors so far. The stock one from 56,000 miles of daily driving, stoplight showdowns, autocrossing and road race abuse (my bad). The second one from... who the hell knows!

I'm too poor to buy a truck to tow my race car to the track like everyone else in the race group, so she has to drive on the streets if she's going to get there. What can I do to help insure/extend my brand new motor's long life? Oil Cooler? Accusump? Baffled Oil Pan? Stop racing? Never! Help an OG out!

Peace...

 

Paul:
just cr00z on the blvd and take her to shows

seriously though, anybody got suggestions. I'm in the same boat.

yoshi - who hates riding the poor man's boat

 

To mister "original gangster": be nicer to your car

 

Thanks for the words of wisdom Homer.

Peace...

 

I thought JUN was helping you out now? Is the second motor your referring to the B16 that you were testing for them?

 

Be nicer to your car .... and service it religiously!

Will

 

Also, in the same boat and looking for an inexpensive but adequate solution.

 

How did the engines die? Did they drop a valve, or break the timing belt?

 

did you broke 'em in properly paul? my original b16a just got pass 87k mi. yesterday and today i was whipping it around sears point pretty hard. 9000 rpm. i was actually scared about oil starvation because you can pull some big G's at SP and the elevation changes really helps the G's too, I was kinda hesitant to go WOT on many exits and taxing the motor to 8500-9000 but it seemed okay. i'm putting in the baffled Moroso oil pan soon. that will make me feel better. my motor's been through a lot of RR events, autox, and probably about 125 passes down the strip. i've been taking it to 9500 rpm lately, other than a little oil burning it seems to be in pretty good condition still. Nothing but Mobil One since 1000 miles.

Anyway, oil cooler, accusump and oilpan will all do. did you think you lost the motor by oil starvation??? it'd be a good idea to check oil level frequently at track events. better safe than sorry.

ps, you're welcome to trade my ultra reliable b16a motor, i'll test the JUN motor for ya.

What? I thought the stock itr motor died at 5x,xxx miles and then you got the jun crate motor... That died as well? Damn. What are you running now? Another jun crate motor?

You gotta pay to play... You know the candle that burns twice as bright lives half as long... Maybe some of those things others suggested like remote oil cooler and baffled oil pan?

Good luck with your current motor... 3rd time's the charm, right?

 

what's the baffled oil pan run ??? $$$ wise

 

I would definetely try and oil cooler, and also maybe try a mugen thermo. Somehow keep the temp down. Heat kills.

 

Oil starvation just wears the parts quickly right? Can't you just grind down the crank, and put new rings on the pistons?

I was testing with that one at the ITR Expo (B16 stroked to 1.8), I have a new B18C JUN crate motor now.

Peace...

 

Not sure how it (crate motor) blew. It would go in for service at JUN almost every week. Free oil meant free oil changes so I did it every week. Also plugs were pulled and checked, as well as timing and other stuff.

It blew on a warm up lap at Willow Springs back in April. Have not driven her since then. Should be getting her back this month. Coming out of Turn 1 at around 6,000 RPM she blew her guts out. The CRX driver behind me (Don Mock), said that at least 12 feet of flames shot out the bottom. It was very cold that morning, your guess is as good as mine.

Peace...

 

HAHA...cool Frank. Thanks. The motor was broken in prior to me getting it (on a chasis dyno). I also drove it around for 1000 miles of easy varied RPM street use before fielding her.

She ran great at LSIR (spanked Michael Galati's old ITR and pulled E30 stripped race cars up thru 5, 6, 7 too (I have all the interior sans the rear seats). She also ran great at Hybrid's Buttonwillow event where Yeah LS and I passes everyone in our run group and lapped most of the field.

I have been road racing since 99 and know all about the R eating oil. Most of us (ITRS) would lose about a quart every couple of sessions. I never lost any oil with the JUN motor (Cosworth rings). I checked it after every session and before starting her up for each session.

Peace...

 

what that blown up traced down to? seized bearings? dropped valves some how? or??

 

From what I have seen thru the hole in the block...the bearings have been discolored from heat and siezed. The head survived without a scratch. The block has a big hole in it as well as a toasted rod and a piston.

In any case I already got a new motor(all new parts top to bottom) and am to pick her up this month. I saw her Monday (after dropping off new Fluidyne) and she's all put together again, still waiting on the brain to come in from Japan.

Peace...

 

Make sure you break it in REALLY EASY. 1000 miles is not enough.

 

was that blown JUN motor assembled in Japan or USA? so it could've been oil starvation (you had stock oiling system?) or... it could've possibly been assembled inadequently...

hmm anyone hear from Glen K, did he replace his blown motor yet?

havent seen you pot in awhile...good luck on the new motor...
keep the heat under control, keep the engine supplidwith oil..and hope all the parts want to work together...peace homie!

 

Assembled in Japan. Stock oiling system.

Peace...

 

I'll be turning 100,000 K miles this weekend in 97 #236,
(I'm the second owner and bought it about 23 months ago with 28K miles on it).

Mobil 1 5-30, water wetter and ARC cap, Mugen pan (for last year's EXPO).
Also Mugen computer last 1 1/2 years, USDM DC 4-1, ... though I've only done 4-5 track days, I do tend to cruise on the highway in the 100-110 range.

I haven't had a chance to check leak-down or compression numbers, but I dyno'd @ 166hp @ 8200 RPM the week before the Expo (10-30 oil, 032Rs and not quite dialed in to what the Mugen computer "liked" for timing and fuel), but I was happy with it for an essentially stock set-up ... and ALL THOSE MILES!

Depending on the compression and leakdown numbers, I may bolt the boost onto this very motor ... sooner rather than later, and still see how long she lasts!

Thats the first thing I said!
I have talked to my Japanese engine builder friends and they've mentioned to me a couple of things about crate motors. The first was the importance of the break in period for a motor a motor like this or even a stock motor like the B18C! I've been told no less than 5k miles before even revving it past the VTEC switchover point! The second thing was the importance of oil levels, oil burning, and piston ring failure!

Lastly, the thing that most stuck out in my mind was the fact that they mentioned that with crate motors you don't really know what your'e getting in respect to engine assembly and balancing and the fact that these high RPM/high compression engines aren't made with longevity in mind!

Anyways...Subi, good luck with the new motor and hope to see you and the fellas at an event soon! Gotta get 814 back in shape....HAHA!

 

Man, that just proves how "tough" the stock motor is compared to a built JUN motor. However, I still love JUN and Cosworth as engine builders.

Paul, I think your stock motor would still be around if you didn't do that VTEC pull up an incline (that's a high load on your motor).
