Fixed - just the vacuum supply hose to LPG safety switch diaphragm - perished again within a year or so !!

Gave it an oil & filter change for the EA81's 465,000km celebration, (ute itself must be close to a mill) checked and regapped its NGK BP6ES's and gave the EA82 NA block, mpfi heads hybrid a glance at, on the shed floor - only 188,000km on it and reco HVLA's,
Don't believe it ! 90,000km on this EA81 and I have not adjusted its tappets

EA81's are the bomb. I'd go one of these over the EA82 I reckon. The ultimate setup would be with the US delivered SPFI dropped on top of the EA81 block with a mild cam

But it'd have to be in an L series for me...

Thought I fixed, still there and now thinking back to a wet day, tar, slipped her into 4WD for take off and forgot the different tyre ratios fitted - felt blody awful like fronts tryin to slip over the rears and was hard to crunch out of 4WD on the L box. Now it feels/sounds like a broken engine or gearbox mount.

Bennie, I think you only imagine EA81 and 2's are very similar. I think I found a lot of small differences in them to stop mix and match. I could be wrong though

Momentary reduction in power??? is the title of the thread.

Don't EA82s suffer from a Permanent reduction in power from the factory?!

Ouch mate!

I was just curious if my EA82 is dying,
as it's adequate and reliable for most tasks, though often taking its time.
It has good initial throttle response though in all gears.
You actually feel you pick up acceleration as you change gears
as this one loves to snore at low rpm.

I even thought of a good name for my Subaru, or my EA82 motor:

*Donk*

As in the burly bloke from Crocodile Dundee 1 and 2.

(bad bloke walks up to one of Dundee's mates)
DD's Mate: "...Want a beer?..."
Bad Bloke: "...Hahaha. Where's your gun?..."
"...Don't need a gun mate, I got a donk!...
"...What's a donk?...
(2 metre, 120-130 kg bloke pops up outta nowhere)
"...DONK!!!..." (and decks the guy

)

what's better about an EA81?
Easier and cheaper to modify/hotrod up?

Is one those things that one can only say after owning a NA EA82 for years...they are not Subaru's best motor. Fact. That is why when people are in a postion to replace them, most go EJ over a EA82 rebuild.

EA81 on the other hand, whilst using old-world technology, just go on forever. Not as refined, pretty agricultural but reliable.

'Hot up'? there just isn't a lot of room to improve Japanese motors in the traditional sense like you would with a holden 186 (thinking cams, carbs, YT heads and the like). Turbos, ECU mods and alloy engines are the way to go!

ooh, bit harsh on a motor that has deliverd about 250 - 300,000km , of infrequent and 'unneccesary' maintenace from when it changes hands for the first or second time. They sort odf deserve a head job, new seals and full timing belt kit by then.

I think every used Japanese car i have bought has always had original dizzy cap and rotor - leads too in nearly every case. Lowest number of kms has been the 187,000 mark, youngest about 15 years old.

Original radiators, hoses and thermostat also the norm. Doesn't take too much to freshen them up for another 1 to 150,000km reliable non leak service life

Harsh but true. You'll probably come across other situations like this in your time here.

You know your Croc D well mate

Kudos.

Sorry mate, have to say it: but if you can give an engine a head job, video it and post on youtube I'm sure you'll be an instant hit!

Nah, just that their design is VERY similar and you can see where the "trace elements" of the EA81 are in the design of the EA82. I still stand by the EA82's existence only came about due to the 80's Over Head Cam move that was all the rage back then in the auto industry. A year to two later they could have had small EJ in the L series, the engine bay looks like it was almost made for them...

Ok, let's leave the EA82 alone...don't want hurt their feelings, may throw a belt just to spite.

What is the most underrated sube motor then? The one that needs some time in the spotlight?

My vote = EA71. Goes like a Dato 1600, and more 'revable' than the EA81.

Any others?

Nah it's all good Sven.

I was just a bit shocked to see such a comment after a serious request.
But I like that about AUSubaru, quick jabs slightly off topic.

Lol El Freddo.

I would have to put the EJ25 up there as most will can it because it has head gasket issues - while true the fix was simple - a set of re-designed head gaskets, therefore that problem is sorted, yet still sticks in everyone's mind!

Yank, I couldn't hold back on that reply to jonno's comment. I've noticed no reply in defence... Hmmm...

My experience with this kind of problem is low fuel pressure. Checking the fuel pump and filter is a good place to start.
