PHP 898 - starting issues

[Waldbjoern]

After some starting issues we decided to pull the head to see what was going on. This is what we found..

Theres a leak somewhere, and just trying to get inputs where to look. We've rebuild the PW's and changed the head shell o-ring. Still seems like its getting pretty greasy plugs. Perhaps the PFP manifold is blown, or the gasket is leaking? Any advice to look next?

WTF? thats a lot of oil. Sure someone didnt get confused and forget the crankcase doesn't get 4 quarts?

 

[Waldbjoern]

Seems to me there's a leak somewhere. I haven't been using excessive amounts of oil..

Sorry, my post was sarcasm.

On a serious note, leak from where? Only source for oil in a 2 stroke is the fuel.

40-1 mix ratio is 40 parts fuel to 1 part oil, not 40 parts oil to 1 part fuel.

Where the hell would that much oil come from? how long was this thing being cranked to try and start it? Did it ever fire?

 

[Waldbjoern]

We did hazel a lot with an epic charging unit, which gave us weak spark and lead to long cranking periods with no actual running. After changing to another CDI the engine ran fine for a period, but now it's acting up again and giving us start issues, especially when cold.

I have no idea. It looks like an oil/fuel mix, maybe a little water in it, but where is all that oil coming from?

I have no idea and am very curoius.

New engine or has it been in service a while and starting problem happend after running it for a while?

Wish I could help, that's just weird. Can't wait to here from someone in-the-know.

I had a Similar issue with excessive oil using amsoil. my power valves would look like that. Switched back to klotz the issue went away.

I also was running the php 898 at the time.

^^^^ agreed, drain tank and switch oils......they run that stuff at a different ratio I've read or it does this

 

[FlightPlanDan]

That's crazy looking.
IMO, choice of oil will not cause that.
If I had to guess, I'd agree with the "maybe" in post #6, water.
Might be as simple as a bad gasket or o-ring.

Post 15 and 20 for sure.....didn't read the rest

You riding in cold water, is the engine getting hot?
If your engine is cold while you're riding, put a reducer in your cooling line to warm up the engine some. It looks like it's not burning off the excess oil

 

[Jetfiend]

Looks like water intrusion to me too, have you contacted PHP and asked them for advice?

 

[Wizards Powersports]

That certainly looks like water intrusion...thick milky oil and water mix...I would check your exhaust manifold gasket, replace with OEM, hopefully that is your issue...

 

[Harbor]

Are you using Amsoil, which one and what ratio you running?

 

[Half flip95]

theres oily water on the top of the dome.
id check your seal on your dome to sleeve- not the shell to waterjacket
if the shell has wear the dome can rock around in there and cause power / starting to come and go

Call Zack at PHP. His support is awesome.

PM " Alex " here on the X or contact Zack at Powerhouse , Alex had similar issues and chased them for a few weeks. PHP guys worked with Alex and got everything straightened out right away. Top notch group of guys right there!!!

what ever it is, i'd check your squish.. there is enough oil / fuel & oil to possibly bend a rod (hydro-lock) a motor if your battery is good enough.

 

[WILKEY]

That's crazy
