Car has freshly built k24a2 with DC 3.2 cams, super tech springs, 12.5 wiseco pistons.

Car was running strong after street tune.

Took car to work, no issues. After letting it cool for an hour, I cranked the car only to hear metallic grinding. Car started and my Link ECU threw me into limp mode, limiting rpm. Took a short log to collect idle and part throttle data. Only issue I found was low oil pressure at idle, around 70 kPa. Car began overheating too.

During this time I heard a metallic chatter, knock, something coming from the engine bay.

Investigation:
Skipped timing? - timing looked fine. No debris/excessive wear on cams, rockers.

Spun bearing? - oil showed very fine, power-like metallic dust that’s magnetic. I consider this to be the “break-in” dust rather than bearing material. Will drop oil pan soon. Will cut oil filter.

Knock?-Data log showed no knocking detected, raw frequencies look no different than when engine ran good.

VTC chatter?-Based on data log: Cam angle vs target was spot on!

Images and log file.

To do:
VTEC and VTC oil filter clogs?
Damaged rockers?-check valve lash, if nut came off.
Oil pump clog?
Check oil pan
Check rod cap play
Thrust washer play?

Lower than normal oil pressure is the culprit here. Will check oil pan; oil pump, rod caps. Any other ideas?

Last change was with Valvoline restore and protect which I hope did a lot of cleaning. Ran the EPR with the VRP for about 15-20 minutes varying the rpm’s then drained it and fill it up with some cheap synthetic oil and a cheap filter to flush the rest of the chemical out. Filled up with Castrol Edge Euro 0w30 and the OEM filter. The quart of HPL EC30 is for some more cleaning. Hopefully this can help with the oil burning. Normal rate of burn is 1 quart/800-1000 miles.

just had my valve lash done. is the ticking too loud should i have them rechecked. The high pitch whistle is what is rigged up from the valve cover to the air box. (Hopefully)

A few more loose ends before she can start and get sent to get exhaust welded! Been a fun project and I’m super excited to finally be done and drive my Honda again.

Been fighting this CEL for over a year now on the hondeezy and replaced a variety of parts (MAF, IACV, EGR, PCV), taken to two mechanics (including Honda dealer), done smoke tests, coolant bleeding, and NOTHING has worked so I’m coming to the community to ask for guidance before I wrap this thing around a tree 🙏🏾
The CEL code would probably help 🤦🏾‍♂️ my dumbass

Retiming my k24a, the first time i retimed it everything went good and aligned properly, this time around i cannot get it to align, it lines up and then when i put my guide and tensioner on the exhaust cam timing mark moves with the tension, then i take it all back off and realign it and it moves out of time upon adding tension again, what am i doing wrong here? like i said the first time i did it i had no issues, this time i cannot get it aligned..

I have a 1998 Civic Sedan (EJ8) so it's an EK Civic, and it's an automatic but I'm going to convert to stick . My budget is $5k-$6k. I specifically want a K24A2 engine, and I know a few things like I'll probably want an EG/DC2 subframe and it's better to get a 6 speed transmission with LSD rather than a 5 speed.

The main thing is, I want a list of parts that other people have used. If anyone else has swapped their ek, do you have a list of parts? Im specifically looking for people who have swapped it for a K24A2, even if you didn't do the manual conversions I'll still take about anything thanks in advance!

Did the oil pan, and after starting it makes this noise

hello All, can anybody please tell me about this engine I found in the junkyard please? Thank you

Does anyone know if there is any relevance to the casting numbers on the rods of a k24a2? I am positive the rods on the left came out of an 08 rbb3. Not sure about the ones on the right.
