My 2004 jaguar will not start gives me the following codes P1611, P1396, P1384, P0405

P0405 is the EGR valve not circulating exhaust gas's or a bad EGR temp sensor .P0174 is a vacuum leak bank 2 .Possible intake manifold leak from the Head Gasket replacement and P1000 Just means in Jaguars case that the code monitoring has not gone into closed loop due to codes being present . P0174 & P0405.

Hey Michael,
How/why do you think you have a blown gasket/cracked head??
....If you have a blown head gasket/cracked head you need to get it fixed ASAP.. Check your oil for cross contamination...( a light cream colored oil indicates water/antifreeze mixed with the oil).this WILL cause major damage if you continue to run the engine..(WATER is NOT a good engine lubricant!!!!) There are several "sealants" or radiator stop leak products... BUT ..cleaning these out of a coolant system is a NOT FUN!!.. Sorry.. trying to "patch" this will lead to more $$$$$ down the road!!

When you replace the rocker cover gaskets, clean the surfaces where the gasket contacts the heads and the rocker cover with alcohol and a rag. Make sure there is absolutely no oil residue on either surface. Use a silicon sealer and spread it on the side of the gasket that will touch the head. Position it and use the head bolts temporarily as guide pins to hold the gasket in place until the sealant dries COMPLETELY. Remove the bolts. Now put more sealant on the surface of the rocker cover and install the cover on the gasket gently so as not to disturb the gasket. Install the cover bolts and tighten firmly but not so as to squeeze or deform the gasket. If dine correctly, the gasket will not leak.

p1396 is a engine managment code. variable valve timing solenoid b malfunction, not a gearbox code. you really need to take your car to someone with access to suitable diagnostic equipment to help sort this problem out, hope this helps,

Did you have the head shaved? If not it is warped and will not seal. To answer you no, it is rare that any sealer is used on any gaskets on most engine parts. There are a few places where oil pans meet seals or valve covers with over head cams that do, but most modern engines do not need sealant on quality gaskets unless there is surface damage.
You did not mention if you torqued correctly and use new head bolts. This is considered very important.

You NEVER in---- my world ---use any sealant in any vehicle
systems-- as it is there for life

It will stop up a heater core
It will stop up a radiator
It will not or seldom be a fix for a head gasket replacement
Get the idea

Don't know what to tell you

Did it shut down from lack of oil pressure to save the motor?

How your going to get that out of the bearings,cam actuators,
oil passages,oil pump,sensors

I think your in BIG Trouble & need to ask many shops what
success they have had with that issue

I say stay out of the parts store chemical isle, with the exception
of LUBEGARD for transmission & power steering additives

Those are ALL, I Repeat ALL, I use & they actually not only work
but are necessary in those two items only (i once owned a trans shop)
I use NO other brands,no Lucus,no genie in a bottle

Just Mobil 1 Oil & Lube Guard & make the proper diagnoses
to all vehicles & do the necessary & painful repairs

ck your coolant for a mixture of oil & coolant & any coolant in your oil. Sounds like a faulty head gasket or bad valve. where any of the plugs wet with oil or coolant? If so head gasket or valves. good luck

Hi there:DTC P1386 - VARIABLE CAM TIMING OVERADVANCED

Possible Causes:
- Bank 2 VVT solenoid valve to PCM PWM drive circuit fault.
- Bank 2 VVT actuator oil supply fault.
- Bank 2 VVT actuator stuck.

The biggest issues with vvts are oil supply issues. Useally debris like oil sludge in oil pickup screen, loose bearing clearances as an engine wears, and oil passages blocked/partially blocked to and in vvts. The first (i always shoot for cheapest potential likely fix) use a good engine flush(2 bottle for our higher than normal capacity engines) follow directions on bottle. Change oil and switch to a 20-50w. Leave out 1 quart and add 1 qt auto ****** atf(highly detergent, more so than engine oil and wont hurt anything) while you have overly ******** cam codes, it may be an issue of apply and blockage that keeps pressure in vvts too long when supposed to release. Most times its ******** cams( like the 1 i am doing right now....try this first and go from there, rememebr to clears codes and give time, you may have to clear codes a few times as it may continue to reset.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

P0405 = EGR valve issues - replace your EGR valve. RE: white exhaust - check door water in your oil, white exhaust usually means a blown head gasket (white smoke is usually steam)
