No Seconds Changes - MD109259 Oil Jet Replacement - 4G15T Forged

After the short lived forged build - /the-good-bad-forged-build-ii-under-knife.html

A few parts were needed, mainly the oil pump, near big end and main bearings and a few smaller bits -

Cleaning the block lots and lots >















MD109259 were tapped out from above the mains.
And tapped back in via the main cap. I was thinking I needed to freeze them to make them fit, but went in relatively easy









< small pin a used to tap the oil jet in with.
The OLD oil jets definitely felt different, the check ball inside, i was pressing it with some TIG wire

















Had to measure from main cap to the block deck, I came up with 200.92mm, I have no idea how much which removed when we got it decked.

Cleaning everything to bolt in the crank and rods
Main caps - 65ftlbs (3 step torque seq)
Rod Caps - stretch 0.0055"





Oil clearance 0.05/0.038mm

RColt Tire Options - RComps - Racing Compounds

Trying to work out where do I start on the tire department, I want to go bigger.

Currently on the Z221, and they been going decent. Set a PB on them.
Running 215/45 and 225/45

Due to clearance issues, rolling diameter and width limitations, I have to be careful and always check these











Fitting the 215s on the fronts posed a few problems. I run a 20 spacer to push the track out. /rcolt-with-rays-57c-gram-lights-17x75.html

B18C2 EG TLC - Timing Belt Installation and Water Pump

Ahhhh what a pain this was, something simple took forever @_@
I think because the B18C is shoe horned into the EG, there is very little ROOM!





But the usual step took place, remove power steering belt, drop undertray, loosen alternator, remove alternator belt, remove the crank pulley (rattle gun action), remove the plug leads, loosen the plugs, remove the rocker cover, remove the timing belt covers.



Remove the tensioner, remove the timing belt, remove the water pump.


And reverse.

Remove the locking nut, and pivot nut then spin the wing nut to loosen the PS pump
I previously rebuilt this for the P72 head

/honda-p30a-rebuildoverhaul-from-b18c-eg.html












Engine mount from the chassis as well as from the block was removed, I had very little clearance.






















New tensioner (I didn't bother installing new cam and crank seal, no patience, engine has 200k km on it







Water pump bolts vary insize, so be careful, I always add some silicone grease to the O-ring. Some people might want gasket sealant that is used for water pumps






I rotated the engine anti clockwise a tad then clock wise to take off the slack.
I wasn't able to do a full rotation counter clockwise, the belt would slip.

The Good & The Bad - Forged Build II - Under the knife

Ouch - 0psi on the oil pressure gauge, drop the sump and find this @_@

The oil pickup was intact @_@
So what is the issue! Later found out the oil relief valve had jammed/siezed, I'm guessing due to this grit... Sad days

















Stripping a good oil pump










Out she comes, getting good at this.






Later i split the oil pump to find this!











Bores look good








She only did 100km









Shiny under there

5th main bearing took a beating.










 100/150km









Thrust bearing clearance issue? Or just that grit contamination





Previous history:
 - block has been decked, bored, drilled and tap for oversize head studs.
 - crank was ground, due to damage
 - head was decked, ported & flowed, new stem seals, lifters cleaned and bled
 - supposedly hot tanked (we also washed everything - no idea where the grit came from)

Current state:
 - loss oil pressure
 - dropped the sump, thinking oil pickup came off
 - found ferrite grit in the sump!
 - popped some main caps and was not happy
 - oil pump relief valve was seized due to this grit we found.

What next -
 - everything re-washed / hot tanked
 - crank polish - looked closely and the crank seemed pretty good
 - investigate the bore, is it worth a quick hone and new rings? or carry on...machinist reckons don't worry (I'm guessing because oil isn't under pressure on the bores, just for cooling.
 - new mains and big end bearings - oversized .25mm

No Limits Track Day - 24/04/2014 - 59.2940 & 1:11.3470 - Zero Fuel and Rain

< Top is an old lap of the long track, bottom is this time

Another track day around barbs. Def need to flip the tires around. Outsides are wearing real thin.

Because I run offset sizes, I can't put fronts to back etc.

/track-prep-z27ag-goes-to-war-iv.html

Top is my fastest lap around the short track, I think.
Bottom is my current track

Final results........I think the damp track got me down. Just wasn't running my hardest. Still very surprised I did a 59. Shat my pants, could have skated off the track.

Ran out of fuel  on the track day, had to drive 20km to go get fuel LOL. A brand I have never used :)
