# 3801111 Longblock Engine | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured long block weighing 1127.2 kg and covering two applications, TWD1240VE and TAD1240GE. It is the single long block across both halves of the D12 listing, TWD1240VE and the TAD1241VE and TAD1242VE pair, which split instead on the injector and the turbocharger. A reman long block is defined as the cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover - the intake and fuel system, exhaust manifold, turbocharger, oil cooler, circulation pump and flywheel housing belong to the complete engine package rather than to a long block. Reman components are restored to technically new condition, with wear parts and anything outside tolerance replaced by new genuine parts, built to a bill of material carrying all design changes so the unit meets the latest technical specification, then tested and painted before despatch. This is an exchange item: core deposit 3804111 is charged alongside it and refunded as soon as the worn long block is returned, and the core can go back once the new one is fitted and the engine is running again.

## 🔌 Function

Supplies the block, crankshaft, pistons, camshaft, cylinder heads and valve gear as one remanufactured assembly, replacing the core of a worn engine while the ancillaries carry over.

## ⚠️ Common Signs of Failure

-   Low or uneven compression across the cylinders
-   Heavy blow-by from the crankcase breather
-   Knocking or rumbling from the bottom end under load
-   Oil pressure falling away when hot
-   Scored bores, picked-up bearings or a worn crankshaft found on strip-down

## 🛠️ Service Notes

-   Transfer or renew the intake and fuel system, exhaust manifold, turbocharger, oil cooler, circulation pump and flywheel housing, none of which are long block content
-   Core deposit 3804111 is charged with this order and refunded when the worn long block goes back - the return can wait until the new one is fitted and the engine is running again
