FR-S Rod knock

^This.

A couple years ago, I was installing 1600cc injectors on my racecar, after the install and priming the rail, the engine would not turn over by starter or by bigass prybay (on crank) long story short, the injectors were faulty and stayed open under pressure and filled all 4 cylinders with c16....so ofcourse I thought I was boned....(by this time im a case deep in heiniken) and I notice a old spray bottle, I took the top spray pump off, stuck the plastic hose into the cylinder and BAM! fuel pumped into empty Heiny bottles.


the point is, when it locked it was not running however it literally would have locked the whole drivetrain if it pulled enough water to bend a rod.


tldr; shit happens, good luck.


*edit* its also pretty awesome to see fuel shoot over the hood when you crank a hydrolocked engine and plugs out.

Just so we are all on the same page I did not bypass the MAF and in the pic the yellow does show where I drilled the box

I don't understand why you would drill the box like that...regardless, I also don't see how it would cause a problem.

you drilled holes in your airbox? why?
resonator hole left open? but its fine like that?

this cant be real, troll post?

I so wish I had a picture of the last engine we got a look at. All four rods were bent at 30 degrees. Bearings were flattened, pistons were in pieces. A truly hydro locked engine will not have a bearing knock, it will have a large hole in the crankcase

Drilling the air box and removing the resonator may be irrelevant to the issue, but it doesn't help in terms of arguing with these people. And argue I would. Argue the h*ll out of them. There should be an abundance of water evidence (and, as you say, salt) in a hyydro-lock situation. Plus all the other good points that folks have raised in this thread.

So, tell me again: Why do we live in a culture where consumers are willing to tolerate this kind of "buyer does our beta testing for us" sh*t? It only ever leads to mfrs. denying that they brought to market an underdeveloped product.

My dad drilled holes in the airbox of his F-150. He said he liked the way it made the truck sound

A likable, louder sound is almost always the only outcome of this kind of mod. Same with CAI, etc. Good for posers. Bad for avoiding from the PD. Zero for performance.

1. That IS knock
2. That IS horseshit.
3. Sorry man

I think they are going to have to pull the black box data to identify what really happened in the motor. The dealership is doing what they do, trying to identify WHY something happened. Politely remind them that their job is to fix it, not waste time playing detective for hypothetical causes and effects. If they believe its in questionable territory, then a scion customer representative can come in and inspect the vehicle and black box data.

This is my intake box.

My friend's had had an '83 Civic that that was hydro locked. Bent all 4 piston rods into S shapes but that was the only damage. Replaced the piston rods and put another 100K miles on the car. Weirdest looking thing to see a bunch of piston rods bent like that.

I have never liked dealerships, reading this just reinforces my hatred.
